This game is really nice!
I think the art and animation is just phenomenal. I love the music, and I liked how it interacted with things happening in the environment, especially during the boss battle. I noticed some of the instruments were proximity based and emanated from the enemies themselves which is just a really rad idea.
I do have to say, and I notice some others might agree with me here, the gameplay is a bit frustrating. I think there could have been some more wiggle room or something, perhaps multiple hit points that you can take before having to load a checkpoint? This was in effect during the boss battle. The nature of the golf mechanic turns something genuinely frightening into a tedious chore. Especially during the stay in the light segment, that went way too far with it and made me annoyed haha. It's a shame because I imagine it might keep some players from reaching that knockout ending. But the gameplay idea is bold, and I understand where it's coming from.
Overall, the delightfully weird and imaginative concept alone sold me on the game and on you being an excellent creator! Keep it up! I'm a fan now, after playing Liminal Ranger and then this.
