Wow, that was some fantastic level design. I really enjoyed this game all the way through, and color me impressed with these freaking levels man. The game is pretty polished too, I didn't run into any bugs. Levels were all decent lengths and the way you teach mechanics works really well. I would say that something like a quick undo or something would be nice, because I found myself having to restart some rooms quite a few times, making playtime add up a while. Really fantastic work here though, props from me.
