Very nice concept! I really liked the game!
For the suggestion part, I think art could be improved but it is still good anyways.. and maybe, you can try making the aim snap to 15 degrees or something.
The game is very challenging and I like that!
good call on the aim!
I am not sure of the exact rotational speed, but it probably isn't a sensible number. Something like 15degrees would make a lot of sense. I will make note for when I come back to this game :)
The art isn't great, but if you look at my old games I'm sure you'll agree the improvement is substantial xD
