There's so much attention to detail here I love it! Being able to run over signs, driving my cart into the water and being surprised when my cart is ruined, seeing the tracks behind the golf cart, it's all amazing!
I remember you mentioning in a tweet how you got the cart to be 3D (using sprite stacking) and I want to say you totally nailed it, it looks great!
In general, the "3D" parts of this game feel so good. The way the ball's shadow tracks under the ball as it goes high in the air is really slick.
It took me more than a few tries on the first hole to realize that when on the green, you want to press X when the cursor is on the marked section, NOT the green section.
Gameplay-wise, at the start I had mixed feelings about what seemed to be a purely probabilistic golf game (move the circle farther, more probability for error, closer = more precise), but in the end I really liked the simplicity of it. I think there are enough golf games with 'power meters' and timing your shot. I was here for a relaxing game of golf and I got it (plus the 'on the green' had the "power meter" anyway).
Really great job, you really nailed it! I ended with a 43 because I did some, uh, 'limit testing' near some of the rivers haha.
