Marble Madness is a unique action puzzle game based on the arcade game. You control a marble and you must roll yourself to the end of several labyrinths. Aside from having to beat the clock, you also have to avoid falling down pits, evil steelies, marble munchers, acid puddles, and numerous other hazards. The game starts out pretty easy, but the later levels are extremely difficult.

Text

This game's text is kind of funny. The letters and numbers are ASCII, but there is a bunch of letters and numbers in the unused portions of the CHR graphics as well. It's almost as if they started with one character set, and then switched later on, but forgot to remove the old one. The forgotten set is not used anywhere in the game.
