Cool game
I really like the music and the levels were pretty fun and look good
The ball falling to the previous hole was a cool mechanic and the 3 undos were nice too (and the animation).
However, the physics seem a bit wonky especially for slopes at least for the web version. Slopes seem to push you back at an unnatural speed/direction. I also happened to find a bug where undoing your last stroke when you were stationary on a slope pushes you all the way down it really fast. It feels almost like the game was developed purely in 2D and the 3D physics was simulated on top of it instead of just using a 3D physics engine to begin with (which honestly seems impressive).
