Excellent game! Had fun trying it on the web, so I had to download it to play against the IA.
Got some issues during the tutorial because I stay too much and FPS dropped down, all houses shooting money non-stop, haha. In-game it was quite easy to win if you rush it, but if you try to buy a lot before attacking, there's no way you can get their houses down, let alone the banks!
A nice entry, more so because it was made with Godot, which I love. I will dive later into the code, just for fun.
Congrats!
