I think the gameplay got a little stale after a while, because I found myself moving between two spots out of reach of the outside projectiles, and I didn't really see the point of the rewind skill.
But the premise is really fun. The way the game switches your controls is really disorienting, and maybe with some tweaks, you could make a really cool bullet hell game.
Also, the visuals are simplistic, but it works really well. Kinda reminds me of superhot.
Overall, it's pretty good.
