Hi there, grat game.
I love the visual style, low poly is always a win in my book. The particles and post processing effects really make everything pop.
My only concern is the difficulty ramping. The first spinner was tought, but once I got trough i memorized it which felt awesome. However the enemies that shoot right after are super difficult. Their fire rate and detection distance are very tough. I think if you are going for a super difficult game its great but maybe give some breathing areas between those hard challenges or even checkpoints.
Im not sure how the game fits the theme, unless I was playing it wrong but I dont think i ever need to use the rewind.
Other than that, the game is very solid and fun.
