I love the graphics of the bird contractors, and the general vibe of the game. I wish that there was a better tutorial rather than just a wall of text you force the player to read, and it was really annoying that when clicking any buttons in Mine mode made me dig the dirt behind the button too.
I also think that it would be cool if the contractor birds dropped little hints on their "perfect dream home" in their request dialogue rather than just needing to guess and check for the hidden requirements for better scores.
Overall, I think it's a pretty cool game that just needs a little more polish :>
