Okay, so I was sick for two weeks and decided to give this a go and here are some results, I'm not gonna play again anytime soon.
I made a rollercoaster from the top of the world to the bottom and it comes back up with turbos and it has a large portion of it under the sea, which you can see through a glass tunnel. Then on top of my house you can also see my GLASS SUICIDE TOWER.
Here's a view from the tower. I built it 3x4 and then a shaft all the way down...with one block of lava. What a way to go at sunrise.
