Very fun! When I first looked at it, I was immediately reminded of ultrakill, though the unique yet simple and fun mechanic definitely makes this game stand out. The movement feels good too, not too floaty or restrictive, just the right amount to feel fun to move around in.

Only one thought, the slomo could use a caveat, probably like a limit on how long you can remain in slomo, and a punishment for remaining in it for too long?  Idk, to be fair the slomo already ends itself when the player dashes to an enemy, so it's not like they can sit in it forever. I'm just being nitpicky lol.

Can't wait to see what else you decide to make!
