Interesting concept, I was very surprised and at first did not understand how to play.
If you want to develop this demo further, then think about this:
- If you make it more difficult, then give the player more predictability, add some additional indication or something like that, so that you can better understand where the ball is pulling and how to influence it
- If you make it simpler, then a hotkey instead of 3 buttons would not hurt, so as not to move the cursor around the screen too much. Another option is to completely abandon the buttons, it may turn out to be a good hyper-casual game
