Darwin's Lab came to me after Ground Zero (G0) started to slow down thanks to all the tests done on it.
For this single player test game, I decided to create my own world. It was to be flat, have a base of bedrock, followed by ample smooth stone, and then dirt. Coincidentally, once the terraforming was done, I was also given a village.
As more and more fun and interesting new items come out with new versions of MineCraft, I'm most likely to give them a try here. If I see a YouTube video with a wonderful idea I wouldn't mind incorporating into one of the multiplayer worlds, it'll be tested intensively in the Lab.
This is a good time to point out that after all these upgrades, there is still enough of a difference between Single Player and Multiplayer to cause an issue with some projects working in Single Player, and not working in Multiplayer. Hopefully, that'll change one day.
Both a blog and a gallery are included which pertain to Darwin's Lab.
