It's a lot of fun to play, and I really like how you interpreted the theme!
I should warn you, though, that while I was playing, the WASD keys suddenly stopped responding...
Still, it's a great game, and I hope you're able to find the bug!
I remember I was on the level where there were two enemies—one you have to parry and one sniper. I think I got stuck between the two parry enemies, and after defeating one of them, I got stuck, but I’m not sure. Let’s just say I was in a mess of a situation where I was surrounded by lots of enemies, so I wasn’t paying much attention—I just wanted to get out of that situation, hahaha.
The only thing I’m sure of is the level, but when I played it again, I didn’t run into the same problem.
I hope this was at least a little helpful...
