The graphics are really nice, but it didn't feel too challenging. However, I'm not sure I understood all of it tbh...

Regardless, it looks great and I'd want to play a version of it with more designed levels

A neat idea, I liked it. The "Scale" part in the Build to scale theme I believe was implemented not good. Though you can say that spending your money corectly is scaling, that would make sense.

You seem to be able to win the first 8 levels by just spamming houses, so there's not a lot of challenge to each level, and it breaks after level 8 and just says I won until the game closes. I like the concept though, and the pixel squares are cool.
