That is a very good platformer, I see you guys put a lot of effort into it, the graphics are great, and the controls are very fluid. Also, the level design is especially good.
There is only one thing that bothered me a bit. At some point, I got into a white-background level, where anytime I fell I got into an infinity trap. That map was a bit too punitive for my taste.
Great job, congrats to the whole team!
