This feels like like an I Wanna Be The Guy style rage game with the amount of stuff trying to kill you and how long the levels are without any checkpoints. I'm not sure if that's what you were going for or not though. If you weren't, some checkpoints throughout the levels would be welcome. I couldn't even beat the first one!
The graphics are quite nice, and generally make it easy to see upcoming obstacles. The audio is solid too. The controls mostly work well, though it would be good to have them somewhere in the description (as far as I can tell it's WASD or Directional Keys to move, Space to jump).
