The character controller felt a bit odd, sometimes too slow or too stiff, but I do like the structure of the levels and the art. It could use some improvement but it's a good base point if you want to flesh out the same concept later.

A good start! I ran into a hole I couldn't get out of, but that just means the game is really realistic. :) I had fun overall though - certainly think there are some ways to improve it, but it has the potential too. I recommend at least setting up the scaling settings in your project options under window, so that it's a bit closer and a better resolution. I'm excited to see more though!
