Context Sensitive
Don't get me wrong, it is a good game, very creative and what not...but it's the platforming and the controls that doomed you.
The controls feel very light and floaty; one jump and you seem to be flying all over the place. Also, for a platformer, I feel that speed is good, but I think you went a little over-board on it. The speed mixed with the overly sensitive controls makes for a rather frustrating and almost difficult playing experience.
