Really nice and fun! I am not expecting the game to be that good but you've proven me wrong. I like the pacing of the game a lot, with the time-slowing mechanics and really fast non-slowed real time it really gives me the vibe of Super Hot. I love that game so much. I also really like the quick resets you've done. In games like these, long downtime due to resets is never a good idea and I think you've nailed it.
A small critique is that I really hope the level graphics are a bit better, maybe some tile sets to convey the scenery, and this will definitely enhance the game quite a lot. Maybe consider doing limited bullets challanges as well? It sounds nice.
Anyway, this is really good I think, so keep on the good work!
