So first I have to ask: is there a particular reason the keys are Z and C?
With that out of the way, I'll also say that: the Flamethrower shot felt like a downgrade from the default shot, you can't strafe when you're not shooting, and that the game's slightly too easy (when you're not equipped with Flamethrower).
The rest I found to be actually decent, there's never too many shitpost-like creations that take itself seriously. When I saw how Marisa was taught the Laser Spell™, I'm sure I grinned.
