Thank you for the feedback! My intention for the pistol was to have it slower to fire if you hold the button, but it will fire as quickly as you can press the button. That was how it worked in Left 4 Dead and I wanted to recapture that same mechanic.
Yeah you're right about the corridors too. I would've liked to have more control over item spawning so I could make sure it would place rewards there, but I didn't find time to go that deep with it.
