This is an excellent example of the simplified game prompt. It has three buttons and one objective, but manages to be consistently fun and challenging. It also manages to feel like a complete game while only using a limited scope. I don't have much criticism to give, this was a really good entry.

Spectacular! Level design makes perfect use of the game mechanic and the progression of difficulty is great. You nailed the gameplay. Maybe it could have resembled a city builder a bit more to better suit the theme but, honestly as-is it's probably better than if you tried to do that. The visuals are probably fine but maybe could use a tiny bit of polish.
