Interesting concept! Did find some bugs where the poligon wouldn't appear but the ball would still collide with it (or maybe it was some other thing I wasn't understanding) Still, good job and congrats on your second ever game!
Thank you so much for the generous comment! I did find out the poligon issue was to do with instantiating the poligon and editing its values without checking if it's fully loaded yet. Interesting how these bugs come about.
