The domino minigame is engaging, but I can't quite get what's the overall goal of the game: I maxed out relationship with all people, but I couldn't see any difference between two and three hearts relations.

I think the game needs a bit of focus, there are three stats, but I only used money to buy food, I also never took the bus because the fare is too high and there's no time constraint so I saw no reason not to go on foot.

I think you took on more than you should have, especially for a game jam. The dominoes was really good, polished and some nice options. I would have stopped there and released. It would have come across as  a nice game, rather than unfinished with some confusing bits added on. Less is sometimes more. Nice job, well done.

Really enjoyed it once I got the hang of it, would just note that it would be good to avoid the walls of text on how to play.
