Really fun game. The concept is very simple but it works & feels good to play.
Ran into a few 'minor bugs' (not 100% sure) where the balls would not head in the right direction at launch but nothing game breaking.
A quick retry (like the r key) could be a good improvement for when you know you missed your shot. so that you dont have to wait for the ball to stop.
Appart from that, really good game.
Nice job :)
