Need to find a game?

Question

Habr

I remember there was a post on Habré for a long time (it seems to be this autumn).
The bottom line is this: a browser "game" (if you can call it that), it has one big text world. You can write your own letters, even texts. The whole world is one big notebook.
Please give a link, the search on Habré did not help me.

"Text world" ? The linker leads to yourworldoftext.com/habr

Answer 2

Answer 3

Damn it! I thought about the implementation of such a thing for about a year :) Yes, a link to the studio, please!
