A few bugs off the top:
-The first crates you encounter don't seem to have any collision detection? You can run right through and phase through them.
-The first green spewing projectile enemy has their AI bugged, where they will rotate back and forth on the slope, stuck in place.
-After acquiring the chaingun, scrolling up to switch weapons causes the game to freeze and become unresponsive.
Seriously loving the grungy meat apocalypse vibe!! Super excited to see where this game goes! <3<3<3
