An interesting start to a game, but as others have mentioned there are plenty of bugs!
You can spam buildings in one place, and there's no reason to place anything other than infinite red building which yields both gold and population. As you have infinite gold you also have infinite time.
People complain about games being exploitable but games you can exploit actually seem more fun, that is to say I had a lot of fun exploiting this game. Maybe you could lean into that.
Also as no one has mentioned it yet, the UI goes behind the buildings when you move. I'm sure you know this but just in case!
