I believe it has potential.  But there isn't a way to change your controls. I love using manual shooting and I play 4 finger claw. So it would be amazing if I could change my controls. Also make it so then the controls can't be locked in a certain barrier when you want to change it. Because I shoot with my left index finger and aim with my right, so it would **** if I had to do it the other way around.

Also, make the upgrades have almost no bearing over your skill. I only played a few games and leveled up a bit and I can already tell that it is going to rely more on what you upgraded/bought than your skill. Stop giving casual players a false sense of being a God in-game. I hate when games do that.
