Absolutely love the art style of this. The graphics are really polished and wouldn't look out of place in a commercial game.
I like the core mechanic. I find that part of the joy of these kinds of tile-laying games is building neat little layouts while also meeting the goals of the game. I couldn't see a way to rotate tiles before placing them, which would have helped with this.
Also, the rewards for building disconnected groups of trees/houses/fields encouraged spreading out the tiles a lot more, which made things look less neat. It would be nice to have a way to split up groups without having to do this. Perhaps the railway lines could count as dividers, like roads in Carcassonne divide fields? (In fact, I couldn't work out whether the railway lines had any functional significance at all; they didn't seem to, although I like the way they looked in the game).
Overall I really enjoyed it though. Just a few mechanical tweaks and a nice soundtrack would make this into an excellent game.
