Great demo!
Bugs I found:
1) if you drop a gun and pick it back up magazine will reset to max ammo, this is exploitable with the shotgun. By shooting twice then dropping the shotgun, picking it back up as soon as you drop it and then repeating, you get a full auto shotgun. Kinda broken lol
2) if you drop, reload and shoot at the same time wacky things'll happen to the gun when you pick it back up, tho they fix themselves as soon as you reload
