like everyone else is saying, sandbox with no time limit would be great. could be allowed for only levels you have beaten, and more time would make levels balanced. overall good concept. take constructive criticism FTW
i love how so many people complain that the game is either too hard or too easy...
makes me chuckle
really solid game, but once you discover how to always own face (there's a way) it gets kinda dull
final boss kicks freakin ass too
goddamn
