Very cute art style and setting. The music fitted the art perfectly!
My feedback is the same as a lot of the other commenters. I found the "tutorial" to be a lot. Might be an issue on my end, but the text appeared in very small fonts, both moving too quickly (as in, no ability to pause) and feeling like it was moving too slowly because it was a lot of info dump at the beginning. So when finally getting past that and getting to play with the menu, I wasn't sure if I was doing it properly after that, only to again see a lot of text. Also waiting for the phone to do something but nothing was happening, so I stopped there. I am also a bit confused of the relation with the jam theme, but it could also because I didn't get far enough in the game to see. I do think this could be a very cute game if wrinkles are sorted out, as seen from the screenshots posted by other commenters. But overall, I think very impressive for a 4 day game jam!
