I've played 9 games from the jam so far and this one is the best, hands down. I appreciated the way you presented the tutorial, and you totally nailed the idle/clicker mechanic for the scope. By the end my island was just gas stations haha! With more expansion and maybe a few other downsides to certain buildings, like having too many of one type too close together or something, could make this into a fine little Steam release.
Oh by the way, the popping sound when placing objects seems to be a bit delayed - it has to be IMMEDIATE. The game feel is so close to perfect.
My one actual substantial suggestion would be to make sure we can move the camera to some extent, because opening the menu blocks a huge chunk of vision of the city. It would be nice to build while having the menu open, although granted you could just close it every time you choose a new building.
