This was a cool game! Mixing golf with just playing around with a physics system was quite enjoyable! One of the thing I noticed, though, was that the game didn’t seem to handle especially fast moving objects well. I felt I was able to glitch the system by just whacking the ball ridiculously fast to the point the ball started just traveling through objects (happens when a physics object travels faster per-frame than a collision object is thick). Beyond that, though (or maybe including it), I enjoyed this game quite a bit.
I played this on one of my recent streams. Here’s a link to my playing your game!
