There isn’t really anything to do yet, but I can see some potential. The gun has a pretty sleek design, and the turret thingy is pretty cool. But I’ve got a bit of advice for ya.
I would recommend making the character less tall compared to the NPC’s
Add some sound or recoil to the gun, and decrease how spammable it is by a tiny bit.
Try to make it so the after-effect (?) of a shot lasts a shorter period of time, or you just get left with some random lines sitting in the air.
