I found My Colony a few days ago and been having fun with it. There seems to be a lot I still not opened in game.

You start on Mars, Moon, etc. with your ship, colonist, and rover. As you build you can expand your Colony to the point of having a economy and even buy your independence from earth (or another real player if you choose.) It seems you can even build atmosphere generators and work your way to creating a earth like planet.

It is free but I did pay the $1.99 to remove ads (banner on bottom of screen only) because I felt the developer deserved it.

This game is on all devices and includes google chrome. It looks like the cloud save function is in beta.
