I would make the game fullscreen so my mouse wont go off bounds; it was very hard to control the player. I found that at times, you can jump properly. The aim with the jump is inversed, when you look down, the aim goes higher, and when you look up, the aim goes down. The playback reverse skill was epicly cool, you can undo the things you've done. And the music gives a chill ambiance as well.
I didn't like the game, but I did find the concept and art interesting.
