Fun take on a tetris.
It was a bit buggy especially the resize mechanic. I think it prevented me from scaling something if it would cause collisions but it was hard to tell how much free area I had to make since the camera is so zoomed out. If the resize fails, maybe you can flash the color of the tiles that would need to be free in order to allow resizing a city.
A lower zoom in limit would be nice too.
Visuals and SFX is very polished. Overall it's a solid entry,
