It's gorgeous, I looked at it earlier in the jam and it's stunning. The one thing that is more of a personal preference is that I love bright tilesets and this one felt really dark. It's not a bad thing and I could see this used in a lot of games with a darker / slower / more melancholic atmosphere, those with a stories unfolding and it already evokes images of cold nights and such. I do however love the trees and bush colors, it's wonderful and it makes me smile and I would smile every time seeing them in a game. The waters are really dark but it's fitting with the theme, so yeah, i'm impressed.
The arts are all scaled to 1280x1280 though, so they would have to be scaled down and I think it would be easier to have to scale them up instead if they were 128x128 in the files ?
