Cool, but could definitely use some more polish. Kind of a bummer that you can't seem to pick up keys unless you're in green mode, but the enemies and walls are in place. It could have just been a timing issue with me playing though.
These are pretty good levels, though I feel like I solved some of them in the non-standard way. The rotation time also is pretty long when it gets towards the end, which could probably be tweaked to feel more snappy.
Pretty cool, but it was mostly rotating, and less of actually moving the character. Could improve it by some sort of staying alive, and maybe also some more complex enemy AI.
