This is an addictive experience! I really enjoyed creating this tiny world and attempting to optimize as best I could. Spending prestige points to upgrade the output I get at the cost of starting the world over makes for a satisfying game loop.
If I had to give some feedback, I feel the cost of purchasing water and fire tiles is a bit too steep. I think maybe half the cost would be a bit more reasonable for both. (Just my personal take!)
Overall, this was a very satisfying game. I’m definitely going to play more of it and go for all those achievements! Great work on this!
