I think the size is something like 64x64, took me bloody ages to do the flattening of the land, the planning, then actually placing the logs and leaves.

I'm uncertain of its difficulty, depends how good you are at mazes I guess.
If you can't do it, just burn it down - that's much more fun.

Enjoy. (And let me know how hard it is or isn't)

Additional Notes

The world save is my server world. It has lots of other things on it - like all of my other projects, projects from Fattermanand Mr.Enlarger, and also a few from Kaito.
