The Artstyle is gorgeous and the game has a lot of potential, its a shame that the story lets that potential down.
It feels like a grand mystery is being set up when you first start exploring and reading notes, and then it never really goes anywhere, you don't get to do or discover anything new right until the ending.
The bulk of what there is to discover and explore is done right at the start and that leaves the middle of the game feeling very empty and bland with the ending just being sprung on you, I understand that this is the result of the limited time you have to work on jam games, and I really hope you keep working on it post jam to flesh it out and add more to discover. I adore the look of the world and what bits of story the game does have builds mystery very well and I would love to see a fuller version of this.
