Player one controls; He will use up to jump and left and right to move. Player two controls; He will use W to jump and A and D to move. Your goal is to collect all of the $100 bills scattered throughout the levels. However, don't run out of lives! When you see a password, be sure to write it down. This will let you continue from that point without having to start over (passwords are not cheat codes, they a unique way to save data). Sometimes you may see special passwords, when you do, type them in to unlock extras!
The backdrop actualy doesn't change when the level changes(Other than a world change). Instead, there is a sprite for every platform and every time a player grabs the $100 bill the level variable is increased by one. The sprites positions are based off whatever the level's number is.
