This was really a nice experience! I felt relaxed at first, then when the screen turned more red then black, with the images inversed, I was intrigued. And at the end of the game I smiled and it was just a great reflection moment, like even thinking about good memories I've had in similar places.
I really liked the animation of the carousel, with the horses turning around, and the inclusion of the arcade game that went with the theme was also fantastic. I think the pacing of the game was good, too, and a good length for what I think you were trying to accomplish. The inclusion of the list helped me feel grounded and gave me a sense of what all is in the game, so while I was just wandering around I still had a purpose. The changing tint to the screen was perfect as well, and hinted at the ending, making it a more natural transition.
For controls, I'm wondering if maybe there could have been a way of indicating that there is something you can walk into? For most of the buildings, it worked out great, but I think there was just one building that was not interactable, but that wasn't just a plain building, and I was a little confused at first if maybe I wasn't at just the right location to trigger that interaction. Something like an arrow that appears could maybe serve this purpose, for instance.
Well done!
