Get More Lives Trick: 
This trick only works in the levels Planet Express and Market Square. Market Square has two Sections in the same area. The total amount of gold that can be collected in this area is 50 which is worth 2 extra lives. Get to Section 2 without collecting over 24 gold in Section 1. Now collect all of the money in Section 2 to get 2 extra lives and then jump into the lava. You will start in Section 2 again where you can repeat the above trick to get 2 more lives each time you die. 

To do this in the Planet Express level you must follow the same guidelines listed for the Market Square level, but it takes more time since the money is more spread out.
