I've thought about this project ever since I saw Minecraft for the first time, and now, I'm going to the extreme and make this difficult project. I have a video here that shows what I've already done in the project.

Here, I've made a house, the part where Littlefoot stood before seeing the Great Valley be revealed by light, the waterfall, the cave and outside the cave.
Gee... I may finish this in a couple of weeks or months I think, including the characters' sleeping areas, some parts of the Great Valley (e.g. rock circle, ravines, small ponds, lots of trees, etc.)
