Just completed the game, it was a lot of fun and I really liked the concept! I just discovered a few things I would change along the way, so firstly I think the edges are too slipery, sometimes I just fell of the edge of an platform without moving at all. Moreover the clock doesn't reset properly if you die by spikes. Lastly you should be able to regulate your jump height, as bonking on something while jumping is just a very frustrating experience.

All in all I liked this entry, and hope to see this game be fully finished.

Edit: I also think you should put in a menu when pressing ESC, as quitting instantly isn't something people are used to.
