You choose random blocks (1) or custom blocks (2).

If you choose random, it does what it says. If you do custom, then you can press Tab to switch land types and hold down mouse to spawn. Press escape to go back to the title screen.

Once it is finished, you'll be able to jump around the world using arrow keys.

I was just testing out some new game mechanics that I haven't tried before. I'm opting out of all categories because I only did it for fun. The best part is that you can create a stable orbit around the world as long as you do not hit any land. If you want an easier time doing this, make a world entirely of water.
