Thanks a lot!
What do you mean with "rotation"? If you couldn't shoot at any direction you were pointing with the mouse, could it be that you had a controller/gamepad connected? Since the gamepad code couldn't be tested, it kinda overrides the keyboard+mouse controls :/
If so, it's really impressive that you finished the game without that or the "brake"!
Anyways, I'm glad you liked it and thanks for playing!
