There is a lot here that could be interesting. The art style and color palette give a really nice vibe to the game, but I found it very hard to learn. I see you added a tutorial, which is helpful but there is a lot more the could be added to the game itself to help players learn the game better. For example, it took me a good while to figure out what the differences between the buildings are, and even now I don't know what any of them do. If you could communicate what they are, either in the art or with titles that would help a lot. Overall making better communication for this game would help a lot. I also found it odd there appeared to be a grid but that the pieces didn't follow it.
