Great game, I enjoyed playing it! The concept of the game was wonderful, I liked all the pieces and how they interacted with each other.
Some things I would suggest are: Health bar indicators or something similar to it, Ability to speed up looking through all tiles, and maybe some indicators telling you what tiles surrounding/adjacent to it are helpful/harmful when placing down a tile.
It does get repetitive after a while because you get the same tiles to place down over and over, but I can see more and more features being added that would easily counter the repetitiveness. However, time is obviously a factor, and I think you did a pretty good job on the game with the limits given by the jam!
