So one of the earlier reviews said this was your first game and I'm too lazy to check. Its very simple, but I do have a few complaints. In the tutorial, you forgot to mention you can wall jump. I had no problems learning that I could, but I'm sure there are a few that won't. Also the background environment and the buildings I actually could jump on looked too similar. Maybe use brighter colors if you make a sequel. That and maybe add challenges like Time Attacks.
