The no clicking challenge works!
Edit: My planet has deformed ice caps because of this.

My go-to challenge is no water run. My only wish is that the screen could be larger for better zooming-in.

Right now I am doing a no clicking challenge, and surprisingly it has gone pretty smooth! And I still click, but only for upgrades.

Edit: I may have had to click, but only for water to exist.

Its a innovative idle game, and somewhat complex. But with some problems like glitches or huge save files. Also, it makes no sense that there are more civilizations than populations in some areas (or you can put it instead). Also, even being complex, it ends up being simple, since the only thing you need to win is to buy everything. But nothing happens if a lot of population dies, or you leave the planet uninhabitable, if you put a lot of humidity, more animals than people, etc. It is really wasted in that regard. In addition, the game lacks a tutorial ... You need to take advantage of this innovative idea, and move it to a better game. I trust you ;)
