Nice game! I do think that having to deliver the messages doesn't really fit with the game. It works thematically, but from a gameplay point of view it feels a little pointless because you've solved the puzzle so you're just burning time for no reason. Other than that, well done! Had to redo a few of the later levels and overall I enjoyed my playthrough. Good job :D

That idea of delivering letters came up as I was making the main road connecting/building system and was too lazy to come up with something else :D. But I might change some things in the future, or make it more interesting for player to come up to those houses...
But overall I'm happy you enjoyed it :)
