Congrats on finishing your first non-tutorial game, that is definitely something to be proud of! It's a really cute take on the golf genre :)
It took me a few tries to understand exactly how to angle the kicks, but it was very satisfying once I had that "aha!" moment. I do genuinely wonder if a visual indicator would be helpful or not, on one hand it would help teach the player how to line up their shots, but on the other hand it would take away that feeling of skillfulness. I'm not sure!
Overall, it's a very charming game. Cat + golf feels like a very cozy combination! The little animations are lovely, I especially like the intro sleep animation. Great work!
