I think most of my feedback for this has already been echoed in the comments, but yeah fun game that needs a little UI polish. Really well made for a game jam and a good idea.
Just so I can write something original, I feel expanding this to Carcassonne/dorf romantik style could be interesting, or just a larger grid in general. I felt the rounds were maybe too short/not enough time for the consequences of my actions to ruin me, compared to the length of a round in something like Balatro (which I think is an inspiration for this?). Not sure about any of that, just thoughts :)
