A free program for Android, by Fazbro.
The world is your playing field in this game. It is a sandbox world, which means that it is completely free to play in. You can move around the world, build whatever you want, and create whatever you want. You can even build a bridge between two mountains, or dig a hole to a beautiful desert.
The only limits are the ones you set yourself. You can set the limits to how high you want to build, how far you can go, and how deep you want to dig.
As you play, you will gain experience and level up. The more experienced you are, the better your tools will be. You can use the tools to build, dig, and even create.
