A fun little puzzle-ish game! I liked the graphics, sounds and mechanics. It offers plenty of interesting choices with the collapsing buildings and a bit of deductive work with the hidden modifier buildings. That part felt a bit like minesweeper.
I wish there had been a tutorial about the "compound" buildings since I built them blindly on my first try. I did better the second go around though, getting a score of 50,400. Great work!
