I don't know how you managed to hook me with incrementing integers, but it definitely worked, I played this chill little island builder for a good while. I loved the palette and the Upgrades Go Brrrr sound effect.
A couple things I'll mention. When I heard the Whoop! SFX I knew there was an upgrade ready, but finding that little blue flag was sometimes difficult. Maybe adding a little blue circle would be enough to mitigate this.
Secondly, I think a game this chill would be incredibly elevated with the right soundtrack -- you could just sit, bop your head, and watch those resources flow in.
