I was curious if the world has a world border, so i went to the end of the main island where the sea starts and began building a stair. A few hours and 11500 wood later i came to the end and was no longer able to build a next floor.
Some interesting facts:
It took me about 2800stairs
While I was building the stairs pretty much people were invisible to me, somebody even started attacking me and I began bleeding, fortunately i didn’t take any damage.
I began to starve from hunger at the building process.
There was an increase of the frame rate as higher i got.
