Oh no, I ended up with a shotgun that had negative projectile speed. It could only kill enemies 2 inches behind me! Beat the wave because the enemy bullets also bugged out and fired behind them. XD
I agree with the other feedback here that a few extra hours of polishing would've really elevated this. Making resolution between art assets consistent and adding names for the perks would both a long way.
Honestly, the backward-firing gun was the highlight of the game for me. If you keep working on this (which I think you should; it's a great foundation), I'd love to see you lean into randomized wonkiness more!
