The level design and difficulty curve needs some work.
Half of the levels are very easily cheese-able by walking in the narrow space between two lasers (or the laser and a wall), making the rewind essentially redundant. Additionally, the final stages 8-10 were considerably easier than the ones preceding it.
That being said, I do think you've got a good idea going here; it could just do with ironing out the kinks (though I understand it's a jam game). The music and graphical style were also very nice.
Overall, I'd say you did a good job!
