Nice work. You packed a lot into this in a short space of time. City builder games are always fun to see and I like the cute visuals here. There is quite a lot to manage with pollution, taxes and economy so it definitely scratches that sim city itch. The UI looks nice and clean. I liked the little details. Some kind of tutorial or a quick start guide would be handy as there are a lot of stats and it can be a bit tricky to figure out what matters, especially for new players - but fair enough out of scope here. Solid entry and great job getting so much working, even down to the sound and music
