I really enjoyed this game! It's like the old nostalgic classic golf mechanics. I am trying my best finish the levels in one try, but at level 5 I gave up. It was pretty enjoyable. It's a pretty stable game too.
Now, first is there's no audio, yes it's in the criteria unfortunately. In the visuals, I think it gives the feeling of sliding instead or rolling or spinning sometimes when the ball is slow; maybe a rendering issue or something. But I love how simple it is.
Now, in theme adherence, it doesn't feel like spinning to win in a sense that it's somehow like a rolling game and also you need to stop spinning or rolling to win. Creativity wise, it's a simple golf game but the gray object as the spin to your game adds to its creativity and uniqueness.
Overall, I really enjoyed it! This game can be improved more with more work. Good job!
