Key issues

[zwzsg]

I changed the keybinds, but my new keys are not used.
I found arrows or WASD move, q change weapon, mouse aim and fire, k toggle decals, but I have no idea how to grab powerup. I would have tried the crouch key, except I have no idea what the old key for it was (and new key is ignored). Seem R does some ♥♥♥♥♥ sound too?

You need to:
- List all keys somewhere
- Make the key rebinding work

The crustacean enemies get stuck in wall, like at least one every wave.

Then there's a hundreds game like this already on Steam, and many much better, so I wouldn't mind if wouldn't bother.
