Ahhh!!!
Ahhh! I'm sorry to say that this game has terrible design flaws and I must ask why you even uploaded this in the first place! It's obviously far from finished. First of all, there is no respawn after you fall, something that is very easy to add and also very important. The hit tests are pretty brutal, and in some of the tighter spaces it's impossible to jump to higher platforms because your character doesn't move left and right after hitting the ceiling. Also, your moving "obstacle" kills you if you hit it's side, which can become terribly frustrating. There is only one level and this is obviously more of an engine than an actual game. I do like your character, however :P Good luck improving it... there's certainly a lot to do :)
