This is basically Aim Labs, and to be honest aim trainers should be fun like this. I will say, I despised moving the camera with the mouse and not WASD, since I'm already using the mouse to aim. The cat is cute too!
Thanks for the honest feedback! I totally see your point about the camera controls — balancing mouse-aim with mouse-camera is tricky. Glad you liked the cat and the 'Aim Labs' vibe!
