I think the idea is nice, but the game doesn't seem polished / optimized enough. The camera makes you go through the ground, going full power on the ball doesn't even bring it past the first ramp, collisions are handled as if the golf balls were made out of stone, things like that.
Nailing the physics on a mini-golf game is a challenge, so it's interesting to see people that still go for it.
Although you can hardly go wrong with a music choice for a golf game, this one seemed to fit it well, good job on that too! :)
