The art is very cute, and I was happy to see a chill, story-driven entry. The timeskip isn't super clear; our protagonist seems to go home and then wake up 3 months later in another city. There's also a bug that caused the train background to keep playing for half the game.
I did feel kinda railroaded toward the ending. Not sure if there's only one ending, or I just happened to get that one. I'm glad the pairing worked out, because I didn't feel they were a good fit for each other and was hoping for a third option.
I think the pacing could be faster and the length is just on the edge of being long enough versus too long.
I'm really nitpicking now and I think I'm beating around the bush a bit. The elephant in the room (to mix metaphors a bit) is that this really didn't feel like an SBIG game at all. The premise isn't that out there, there's no super weird twist mixed in, and it doesn't have a bizarre style or janky gameplay. It feels like a game made in earnest for a more normal jam.
