I really liked this idea! Taking the word "rewind" to mean nostalgia and retro games is a super cool twist that I haven't seen done much. I think my only nitpick is just that I was a little confused when playing since I figured you were just supposed to play through a bunch of different retro games (and you were "just trying to get a high score" like the evil video game said), not beat just one game. I'll admit I wasn't skilled enough to beat it and see the ending, but I think this is a super cool concept and with a little more polishing and content it would make an awesome full-fledged game! :)
