Game worked just fine on my laptop.
The idea is pretty cool, but I'd like to see the game developed a bit more. Fix it up so that the graphics are better (I personally don't think this works very well as an 8-bit game, I think a cartoon-y vibe would be better), the animations are smoother, and make the game more of a puzzle than just a "go here and hit this button": there are maybe two places where you can screw up and need to use the rewind feature (very cool idea, by the way, and I'd love to see it ACTUALLY play in reverse, like a VCR rewinding), and it would be cool if you threw in some actual puzzle-solving tactics that would help to make this game more memorable.
