Fantastic game, probably one of the most elegant and innovative game concepts out there. Just by using the concept of "rewind", you made a game that is simple, fun and exhilarating. Keeping an eye on the red arrows and green nodes, while barely dodging the arrows with your rewind ability feels really good.
Only complaint I have (VERY minor), is that the red arrow sometimes spawn kill your green nodes, making you die immediately.
Other than that, fantastic entry to this jam, probably one of the most creative one.
