Triple G.
I like the concept, but the par is wicked difficult to meet. On the rare occasion I got par or under, it seemed like an accomplishment. Maybe you should make it so and add medals. The physics stayed rather consistent throughout the game.
All in all, I like it. It's an interesting twist on an old classic. I'm giving an 8 though, because of the difficulty and the pointlessness to it all. This isn't the kind of game where I appreciate a randomness to it, this isn't the sort of thing that should "just exist". Give gamers a reason to play this.
