Hey, thanks for trying it out. I agree with the points you brought up. Did you try adjusting the mouse sensitivity though? One thing I wonder is if people will forget that mouse sensitivity is a thing because it's not your typical mouse look kind of thing. I tried to make that more obvious. Either way, it is the kind of thing where you get better at it with experience.
Making weapons that feel good instead of sucky is one of the major priorities, as well as making enemies that are good and not sucky.
