Use the arrow keys to move and get to the other side of each level. Red sends you back to the start of the level, you can stand on black and on green you can climb up/down, use as a sort of launching pad or but beware, it is able to slip through and if theirs red underneath, you could be in trouble on it!
Basically, all I did was add some new levels and some music. song (idk the name or who by) ty Bob_McGuffin for making the awesome game for me to remix!
