Thank you for the translation. So the maps are also available for the free and Open Source Minetest equivalent which doesn't have height limitations? Great if true!
Yes, I've used this in the past, though it can take a while for maps to be generated from their website, and the API is rate-limited. It's quite impressive overall, though it could use some help, especially as buildings are quite bland.

It takes a really long time to cross the generated city, even when boosting the in-game speed. That goes to show how much more smaller videogame worlds really are in general, especially when those are walkable.
