Thanks for the feedback. Guns work like they normally do, point and shoot, but traditional reloading is replaced by recalling your bullets back to you activating each weapon's recall ability. I suppose detailing what they are in game or on the project page would have been helpful but I can list what they do here.
Revolver - Recalled bullets rise for a moment before locking on to the nearest enemy weak point (usually the head) and firing a second time.
SMG - Recalled bullets sprout sawblades that deal contact damage while also gaining a slight homing effect towards nearby enemies on their return.
Shotgun - Each individual pellet creates a mini explosion dealing AOE damage to any nearby enemies.
A bulk of the player's damage comes from these abilities. Shooting enemies directly generally softens them up for the recalled bullets, but you can damage and kill enemies just from shooting them.
