Weapon switching is slow, extremely slow to the point of being deadly. Crosshair seems to be a lower than the actual shooting point. Slashing range feels too short.
The idea is very cool (haven't played Cult vs Gal), and blasting giant holes in enemies with shotgun is pretty fun. Shotgun seems OP in general, but at the same time the level design seems to be intentionally "fuck you" hard, with enemies around both corners.
Cigarette smoking mechanic is cool, as a smoker I appreciate the representation. Needs more ciggies though cuz the level is extremely hard.
And the music is... I don't mind it, but it changes midway to something very different, which is weird.
I hope you keep working on it, it's very promising.
