Shouldn't Nyan's PopTart be pink? I know, you're probably working on that. But, in the place where the levels will be, I think the camera should just follow the player as usual, because the camera was panning out too far and it made everything so tiny, and your text was hard to read. Of course, you know best, and I'm definetly not trying to tell you what to do, just giving some constructive feedback.
Can you hit me up when your game is ready? I want to share it in Nyan Cat fans site, [link]
