Very well-designed game, despite being short for now. Really good work with the different power-ups, how they are used in the small level. The dashing power-up was a bit difficult to get first, since you get the impression that you're supposed to gain enough speed and jump to the distant platform on the left and not the one high up in the air.
Especially if you're planning to make this further, we'd like to see it in this year's Game Development World Championship!
