Press up arrow to jump. Use the arrow keys to move. Push down arrow to duck. Dodge Mudds for thirty seconds, and then stay alive as long as possible to beat the highscore! Changelog: V1: made main game with mudds, 1 music track lives, score counter, highscore, rock, jump sound, main controls. V2: added 10 new music tracks and music selector, new types of mudds, new life system, duck ability, deleted jump sound (due to annoyingness).
Mudds are the enemies. Thanks to bananawholikespie for the basic idea (and the rock).
