Simple but fun! I would recommend making the bounce a little more random so that you are encouraged to not just bounce between to corners which right now is the optimal strategy, or maybe try something else to encourage bouncing between different corners like trying to get a certain amount of points in each corner. Maybe both! The controls and difficulty felt good, but I would like a little more of a grace window for bouncing. Great work, super creative and I had a ton of fun!
Thanks for the comment! One thing I was heavily considering was lights on each corner and once you bounced in a corner, the light would turn on and you couldn't score again in that corner until all the other corners were hit, at which point the lights would reset. Felt too cruel for a first play though.
