I really enjoyed the tone and style of this, and you all managed to get an impressive amount of content in in the short timespan of the jam. I thought it had a very unique identity from an art perspective, and kudos to the musician!
As for a bit of constructive criticism, I do wish that the game had more interactive elements. I imagine this is largely inspired by visual novels, and I know that the narrative is the main incentive for those kinds of games, but I didn't feel like I had much control of the narrative or many opportunities to make choices. I know this was a very short game jam, but if you all are continuing the project, I would definitely consider ways to give the player an opportunity to make meaningful choices that affect the narrative.
Overall this was a neat narrative experience. Well done all!
