Really good game, it also feels very polished and looks very good. It really enjoyed playing it. My only real issue was the length of the level / lack of checkpoints. You spend like 3 minutes getting through half the level and then you get to the purple switch gravity things. Since I didn't know what they did, I ended up dying and had to restart all the way from the beginning. I also think it would be interesting to see how the game worked if the AI also jumped automatically. Nice job on the game!
