Use arrow keys to move. As of now there are eleven difficuly levels, and one fun excuse for a level that you will most definitely complete on your first try.
All movement and gray block functions by LN311211, all red block and yellow block functions by me! Update 1.1: Literally two years since the project was released, and most likely two years since anybody has played this lol. 4 new levels added, and working on water levels, but I suck at coding so we'll see if I can actually do it.
