This is a very creative game. It's got a core platforming concept that's really well done, followed by several others like teleporters (which feel like the portals from Portal, which is never a bad thing), breaking stuff by flinging yourself into it, lava pits of death, windows (I love breaking windows in videogames, it's just so satisfying, and I'm glad I had an excuse to do it here, too). The only thing I can think of improving is that maybe it was too annoying to redo the little section right before the bossfight everytime I died to the boss, but I was still able to beat the boss, and I still had fun, so maybe that wasn't too bad. It also would have been nice to have a button like R to kill your character in case you got stuck, but overall this game is really great.
