I love the push-and-pull of rewinding. It is useful in the moment but spawns troublesome enemies, letting players choose how much risk they want to take.
The knockback felt a little too strong. Also, did the enemies loop too? It seemed like many of them just leave the screen, which leaves me wondering why I should bother shooting them at all instead of just dodging.
This game is pretty addicting! I'm averaging around 40 seconds.
