I didn't understand why I could only rotate at certain times. Also I feel like the WASD controls should stay relative to the cue ball so that you don't need to press each button twice to be able to move where you want. Also the camera being able to go out of bounds doesn't look very nice and it took me a while to get back before of the keys not going to the directions I expected.
I think this could go far and be really interesting with a bit of polish.
