Walkthrough:
LEVEL 1
Kill the gargoyle. Right click the obelisk to the north. You will receive the form of the feline fighter, and the door will be unlocked. You can also get the wand of fire from the corner. Open the door by right-clicking it, and go through. There are a lot of the walking plants around. After you kill one, make sure you pick up the float seed it leaves, you will need quite a bit of them. Note that you can open doors with just bars on them, the doors with a weird symbol cannot be opened. Find a door to the south and open it. Shoot the floating chest with either a wand of fire or shuriken if you have it (about 3-4 shots). Get the silver triangle key from it and put it on the pedestal to move the throne. Don't enter the teleportal yet. Head east through an openable door, and open a door to the north. You will find yourself in a place full of mud, which will cause you to lose energy if you walk on it. To avoid that you must drop float seeds to create a bridge. You can go directly to the north (by building a bridge) and you can find a triple-fireball wand. In the north-eastern corner of the mud area is an entrance to the shooting heads. Run through them, or try to sneak through (There seems to be a certain pattern to doing them so that they don't shoot, but since I am not totally sure, I cannot put it here). Get the shuriken on the other side. The shuriken is perhaps the most useful item in the game. Continue down that passage. By the three fires shoot each of the floating symbols above the fires 6-7 times with the shuriken to destroy them. Once all three are destroyed, the fires will disappear. Kill the 3 monsters. Get the statue head in the south-western corner of the area. Go back to the teleportal you uncovered earlier. Enter it.
LEVEL 2
The bat-sacks are pretty tough considering that you cannot use the cat form since he loses life just by swimming. Therefore, just run by them all. Go down the passage until you find the bob and pull it. The level will be drained and the bats will no longer be able to get you. Start backtracking and enter the first passage on the left. Get the skull from the pedestal. Now return to the main passage, until you enter the skeleton room. Put the skull on the headless skeleton. He will come to life, so kill him. This opened a new way to the north east. Get the magical sword and Madrin Armour from the room beyond, and open the door. Get the statue head which lies in front of the teleportal back. Enter the teleportal.
LEVEL 1 AGAIN
Head west, through the door. From this area, head north, through another door and enter the teleportal there.
LEVEL 4
Head west. In the first big room there will be a broken key on the ground. When you pick it up, you will be blocked off and surrounded by goblins. Wait for the stakes to recede and slaughter the goblins. Head to the north-western part of this level (past the barbecued corpses) In the north-western chamber, you should find a way south, there in the west fork of that passage, you must recover statue head. At this point you should have 3 statue heads. Go to the north-eastern part of the level. It will be a big area of water. Change to a human, and swim to the island in the middle. The island is divided into 4 parts, each part has a headless statue. You can find the 4th head right besides the west statue. Replace all the heads. Stairs will be revealed. Go down.
LEVEL 6
From the entrance, kill all the goblins and go through the door. Destroy the chest in the south-western part of the level for some potions. You must find a room with a river of goo and a row of statues behind it. Shoot the flying symbol twice to create a bridge over goo, and eliminate the wall. Proceed through the corridor, and kill the four-armed skeleton. The best (and only?) way is to get him stuck behind a corner so that you can shoot him with the shuriken, but he cannot or will not shoot you. Killing him with the shuriken takes extremely long, however. Get the dragon horn from chest to the north west of where the skeleton was. Talk to obelisk north of the skeleton for the pixie form and to unlock the door to the north. Open door, go through teleportal.
LEVEL 7
There are four side rooms on this level (two east and two west). In each one there is a floating symbol. Destroy all four of them by shooting them with the shuriken. The blue-robed monsters on this level take your power away, so watch it. After all four symbols are destroyed, a new way will be opened to the north and another four-armed skeleton will be there. Try to kill him the same way as the previous one. Enter the teleportal further north.
LEVEL 11
Talk to the prisoner in the second cell. Proceed down the hall until you come to the room with two doors. Go through the unlocked door, and pull the chain to make the opposite door open. Go through the now-unlocked door. By the barrel, you will have to change into the pixie to jump over it (the other forms seem not to fit). You will now be in a square room with a couple of werewolves. Go south and take the western fork. At the end of the corridor you will end up in a room with blue, floating eyeballs. Pull the chain in the south-western corner of the room to raise the cage and expose a suit of armour. If you want, you can get it, but you will lose a bit of health in the process. The blue clawed monsters here are pretty tough, but they will not shoot you unless you are totally exposed. If you move behind a wall, and then slide out until you can shoot a shuriken at them, you will be able to eventually defeat them. Again, this takes a very long time to do. Go east from the room. Again, use the pixie to jump over the barrel. Go to the end of the corridor and open the big doors to the east. Kill the monsters and get the frost wand and silver sword (optional). Go north. You might want to go west first, since at the end of the corridor there is a silver armour. The stairs in this area are useless since they lead only to the wine cellar which has absolutely no point to it. Now go back to the big room which had the silver sword and go east this time. Go down the stairs.
LEVEL 12
Go south from where you appear and take the second right. Open the big doors. To the north of the huge throne room (eventually and after many fights with wizards and gazers) is a blue square which, if you stand on it for a while, will give you full power, but this is optional. Exit to the west from the huge throne room. Go north and down the stairs near the end of the long corridor.
LEVEL 13
Go through the north door. Go west from the square room. There you will encounter the Werewolf King. You must defeat him. He has a strong spell, so the only way is to get him stuck. You might want to use some wands on him to speed things up, since he takes a hell of a long time to kill. Get the obelisk tip and staff of power after he is dead. Put the obelisk tip on the obelisk to get the Opsis form. You can open the south-western room for the cup of power. You can also destroy the chest for a light crystal and a Caun sword (for the pixie). Open the northern door and enter the teleportal.
LEVEL 7 AGAIN
Use opsis form to fly over the fires. Change back and kill yet another of the four-armed skeletons. Open the door to the west. Go north. A new teleportal should be uncovered now, and one of the stumps should be an obelisk. Enter the teleportal.
LEVEL 14
This level is big and useless. The bombs strewn all over the place are just weapons, but they might be handy. Head north from the start. Don't take the north fork when the passage turns west. When you end up in wide hallway around a square in the middle, turn north. Open the door on the northern side of the square passage. Turn east. Follow the passage to its conclusion. Defeat the slaver with the mace. Right click the tap by the Tree of Life to restore it. Enter the teleportal.
LEVEL 15
Hug the right wall, take the first right. Right again and head south. From the southern chamber, head to the east and don't go north. Keep going east. You should end up in a passage which quickly goes north and then turns back east. Continue along this passage and open the door. Run through the fireballs and fireball-shooting monsters (staying on the eastern side of the place might help). Head north and you will come to a run with green sludge. Use the opsis form and float to the west. Open the door and grab the obelisk tip from the ground. Go back to the room with the sludge and float to the new way which opened to the north. Replace the tip on the obelisk to get the frogman form and create a teleportal. Step into it.
LEVEL 7 YET AGAIN
Just find your way back to the chamber with the teleportals. Step into the new one.
LEVEL 16
Go north from the start. Take the third left until you reach a lake of acid. Defeat the spikeballs there and fly over the acid northwards. Get the gate key. Exit the acid room to the west. You should probably go west, then south and fly over the acid with the opsis form. There is a suit of water armour in the north-eastern corner of the big acid room, in a chest. It might come in handy underwater. Return to the little square room in which you appeared after you exited the previous acid room. Take the first north and turn southwest in the big room there. There is a trident at the end of this corridor. It is quite an awesome weapon since it has the range and the power. Go back and this time go east from the big room which had the sludge monsters. You will need to use the gate key you found earlier to open the grate to the east. Use the frogman form and dive in the water by clicking on the bottom of the height bars on the side of the play window.
LEVEL 17
You should appear in a big square room with four exits. Go north. You should come to a square room with a little unexplorable square in the middle. You should use the frogman's electricity power to kill the manta rays. Go west and west again from the next room. When that short corridor ends, go south, and go straight south all the way to the end of that long corridor. Don't take side passages. From the end of the corridor, head east, not west. Follow the corridor to a small square room. Head west and west again from the next room. You will come to a room with a throne, two blue ssairs (snake-like creatures) and a crab monster. The crab monster is the boss of this level. He is very tough so get him stuck around a corner. After you bump him off, look behind the throne and pick up the water tablet from right in front of the teleportal. Enter the teleportal.
LEVEL 18
Put the water tablet from level 17 in the river of acid. The ssairs will no longer attack you. Go west and right click the obelisk for ssair form. Enter teleportal.
LEVEL 7 AGAIN
Again, make your way back to the room with the teleportals. Enter new teleportal.
LEVEL 20
Head north. Take the west fork and keep going north until you find a room with a chain. Attack the symbol on the chain with any weapon to open a way to the west. At the end of that corridor, get obelisk tip. Return to the entrance. Go east. Follow the corridor/rooms to the north (there is really only one way to go). Use flying creatures over the mud and lava. You can kill the steam spouts. Bump off the annoying monsters. The passage will turn east. Keep following it. Enter the first passage to the right. Run through the fireballs. Follow the corridor to the end. You will come to a chamber in the south-eastern corner of the level. Get two boulders from this room and put them into the middle north and south niches, one in each. Pull the chain that will appear. Go to the east and enter the teleportal.
LEVEL 21
Go south and follow the passage. Head east and east again from the next room. You will come to a frog mouth on the wall. Change into the Caun (pixie) and cast a bug spell into the mouth. Follow the passage north. Follow the long, thick passage to the east, then south until you cannot go south anymore. At that point, follow it north west. Take the first fork to the east. Go east from the small chamber you come to. Follow corridor and get hourglass from chamber. Return to thick main passage. Follow it west and head south until you find yourself in the south western corner. Place the hourglass in the southern niche. Put the obelisk tip from the previous level on the obelisk. Get the form of Grost. Using Grost, go straight east and punch the eastern wall (the one made up of pebbles). Head straight east. In the northern corner of the room at the end of that corridor you will find a teleportal. Take it.
LEVEL 7 YET AGAIN
Once more, find your way back to the room with the teleportals. Take the teleportal in the middle.
LEVEL 22
Go south, then west, and then north. Go east from the room with the green gazers and lake of blood. Then east again from room with four exits and three pedestals. Go east immediately after the corridor opens into a room. Open door to the north. Go north and kill the lightning-shooting stick (preferably with Grost). Go west and south, pickup the blue bone crystal. Return to the central room with 3 pedestals and place the blue crystal on the blue pedestal. Dive anywhere in the blood river with the frogman form, but preferably from the room where the green gazers used to be.
LEVEL 23
Proceed to the west into a room with many of those squids. Go north from that room and surface in the room to the north.
LEVEL 22 AGAIN
Fly with one of the flying creatures and kill the red heart on the ceiling. Drop down and get the red crystal which will now be there. Dive back down.
LEVEL 23 AGAIN
Make your way back to the river and surface
LEVEL 22 YET AGAIN
Return to the room with the three pedestals. Put the red crystal on the red pedestal. Go north. Take first right, follow the corridor until it widens, then go west into a short corridor. Get the stone sword from the ground. Return to the main corridor. Go north this time and go west at the end, into the room with the stone knight. You should definitely use Grost here in order to minimize the damage from the fireballs. Give the stone sword to the stone knight (by right clicking with it on him). A way will open to the west. Go in and get the flesh crystal. Return to the room with the three pedestals and place the flesh crystal on the brown pedestal. A teleportal will appear. Go in.
VESTE'S CHAMBER
Change into Grost, and probably give him the Trident of Might from level 16. Before you kill Veste's first form, you should wedge yourself into the corner behind him, so that you will be able to hit him even when you are getting tossed around by fireballs, etc., and he will not be able to push you out. Attack his wizard form. He has (I believe) 5 forms other than his human one, and he will change into them randomly. Of course, you have to kill all 6 to finally defeat him. His forms are:Old Wizard, Green Ssair, Slaver from the mines, Four-armed skeleton, Underwater crab monster, the Werewolf King and finally, a Gargoyle. His last form is always the gargoyle. It is extremely tough, so you have to make sure you are wedged in pretty good. You will lose a lot of energy, even with Grost, so a quick healing with the pixie (if you are fast enough) while he is changing forms could be crucial. After the gargoyle form is dead, you will get the endgame animation.
Notice your grandpa has a claw for a hand! Woooo...scary stuff, kids!
The End
