Graphics fit the game really well and the platforming itself was really fun! I also liked how you designed your levels around the "warp screen" mechanic, it really made me think about where to move my character. There's two areas I see for improvement though - One, add a short grace period (like 0.2 sec) for jumping whenever you run off a platform. I often found myself not being able to jump because I ran off the edge right as I hit the jump button. The other is that despite all the other cool stuff in the platofrmer, I didn't really see a rewind mechanic this game. Overall, nice entry!
