It's pretty annoying when you have to hold the right click button every time when you want to aim your enemy. Maybe you should disable that right click to look around and just use your mouse left and right to look around (no need for right click). Also, maybe you should added some variety of the upgrade, like new weapon or something.
Thanks for the critics, I will add a toggle option to lock/unlock the right mouse button in the next version and of course more stuff will be added as well. :)
