Hi, I've been playing the game :D and wanted to share some feedback with you, hopefully it's useful to you :)
-The main concept and the visuals are pretty awesome and I really loved them.-Adding more info about the population growth per turn would be great.
-Adding some extra difficulty/ objectives could benefit the game.
-Doing some polish on the visuals (adding particles or animations to lava, water, etc.) and gameplay (adding a tutorial, etc.) could make the game even more appealing.
In conclusion, the idea is great and I hope you keep working on it. Hopefully this is useful for the development :D, also if you could subscribe that would help me a lot :)
Regards
