Cool game. Although I have to say, the zoom in/out behaviour when your mouse is near the edge of the play area, and how that affects the angle/power of your shot, AND how sensitive it is, is utterly f***ing infuriating!
Checking your itch.io page and noting that that game has been available for over a year there, I find it hard to believe that nobody else has mentioned this, so I can only assume that you simply haven't bothered to fix it... and that blows my mind!
