How did you manage to put these sprites together in such a short amount of time? And the shading is also great. This is one of the best looking games I've ever played in a game jam. The audio was also great, but the 3d effect on them was a bit irritating.
The gameplay was fun, but a bit awkward at times. The ice physics are strange because it prevents you from moving, and I think the springs should have a set height instead of letting you hold space to increase the height. Also I think a bit of feedback would've been nice. At first I wasn't sure if I activated the checkpoints.
But those are just minor issues. It's still a great game.
