I had a little trouble understanding where to click buttons at first. Like for example to buy food you have to click where it says 50$. If you're working in Unity, consider using canvas buttons, that makes it easier to see what's clickable on screens like that.
Felt like an engaging loop. It was fun to get to the point in the beginning when you could stop working and just play concerts for your living! Would have been cool to have different songs for each of the different stages.
