Walk through everything (test mode):
If you get stuck while in test mode, or you need to walk through any solid objects, simply hold the Ctrl key down and walk through it.
Change Variables/Switches In Test Play
While in Test Mode, by hitting the F9 Key, you will be able to access a debug menu that allows you to change switches from ON - OFF or from OFF - ON. It also allows you to change the value of any variable. This saves you the trouble of going in the game, and back out to change the commands.
Increase Text Message Speed
While in Test Play, at any time by holding the SHIFT Key, the text speed will be greatly increased. (This is useful if you are trying to skim through lengthy scenes).
Reducing Lag
You may notice that in events that have a lot of complex coding, or events that call others with complex coding, tend to lag when the game is played. This makes gameplay very annoying. To prevent this, insert a Wait of 0.0 seconds before and after the Call Event or group of complex coding. This will remove lag almost entirely. Making gameplay much more enjoyable.
