Nice little game! I feel like the first 3 levels were all very similar, basically being the same solution each time.
The rewind mechanic is a cool idea, how it doesn't affect you is a refreshing take on all the other rewinding games. There is a lot of room for more mechanics here too, like maybe moving things around to use their effects in a different location.
I wish there was more depth, but as a small game it does its job. It left me wanting more, which is a good thing!
On the final level, I thought the game had broken or crashed. I was just about to close it before the (enemy?) came out of the wall. Which was very cool! Just maybe reduce the delay, or make it more obvious that the game hasn't broken.
Reversing back to the beginning of the game was cool, and it could be developed into something unique too. Going back to previous levels to do different things? Unless that is the case, then I missed it.
Visuals are great, especially for such a small palette. Audio was nice, but got a little bit repetitive over time.
Was the one level not connected on the map accessible? If so, how?
Overall a nice little game, I would love to see more with this!
