Good little platformer game. :) I think I have not played a game yet where it was important to keep track of the time or otherwise you'll get punished. I liked that mechanic! The only thing I would complain about is that you are stuck on the edge of the platforms. You used Unity right? If so there should be an easy fix for that: Create a new Physics Material in your Assets. Put its "Friction" and "Bounciness" to 0. Attach the Physics Material to the player collider where it says "Material". E voila your bug should be fixed. :=)
