This is amazing, and the art-style is so cool! Love the way the movement controls work. But If i would not have know it was for a "rewind" theme i would never have knows i had to press the R button, i was stuck and just give it a go. Reminding the player in game in the first level(s) of this would be a must. And like other say i would have loved more levels! really cool game and the look still so simple but yet so amazing! very well done! I try my best to give feedback that might help but the only thing is the "R" button really, other then that its great!
