Nice to see a local multiplayer game in a jam!
Like some of the others have highlighted, i think some rules / differences in tiles would have been nice. Having some agency and choice in where i could place tile would feel a bit more engaging than a hidden value attached to a spot, especially on such a large grid. Perhaps a smaller grid could have helped alleviate that? Not sure!
It's a fun concept though, i liked the music and think with more refining and something to base your descisions on, it could be a neat 'lil game.
