Really good gameplay idea, very minimalist but interesting strategically. IMO it has potential for a full game. That's the kind of game that sells on steam (simple roguelite strategy game).
The art is great, I love the small characters walking between the towns. Music is very good too.
The only major downside is balancing. On my third run I stopped playing not because I lost but because I was producing thousands of resources each turn and had 20 times the required resources when a new "quest" begin.
Minor problems:
- The UI for combos is a bit confusing, the white circle should be on the boosted locations, not on the location that was just bought
- The camera moves very slowly vertically
- wasd/arrows to control the camera would have been nice
