Use the Arrow keys to move around. Blue blocks are ok. Orange blocks you can stick to by holding the up arrow when you're touching the block from under. Green blocks are bouncy blocks. Yellow blocks are wall - jump blocks, press the up key, and the right/left key when on the side of the block.
Thx to mario490. I basically remixed the entire project and made 2 changes. 2!!!! Also, this game can get super challenging, so... And every time you play the game it will produce a different part of the full map. If you would like to play the full map, go to the see inside button and play the game inside there.
