A solid idea that's maybe muddled a bit by the controls. I liked the concept, but for the kind of precision the time limit and level design requires, the controls aren't snappy enough. Specifically, the slow acceleration made it difficult to make longer jumps onto precise points. For this game, I'd have liked to see controls that respond instantly to my inputs for moment-to-moment corrections.
Also, the camera moved a bit too directly with the character's movements, creating a bit of a jarring effect, particularly with jumping. Some y buffer would probably help a lot.
Overall, I think this could be very fun with more sensitive controls.
