Cool game! Satisfying little gungeon with good controls and the difficulty was spot on. Loved your little assets, the colour scheme, and the different sprites/circles to show the pause effects.
Couple times some of the baddies would just turn invisible? I'm not sure if that was part of the mechanic. Would have been nice to see the rewind just use the progress bar and no cooldown - sometimes i'd press it quickly once and get like 0.01s of rewinding and then i have to wait for the whole cool down to use it again.
Well done, whole game ahas a really nice vibe to it, very cohesive styling and well polished!
