This is sort of a round pyramid with lava around it (I am giong to remove that) within it multiple layers with houses and shops and buildings etc.

there are also 10 houses outside and a little temple with a secret door to a little chamber, but i haven't done anything there yet.

You can also go to a giant 'me', also with a secret door and a train to 'my head'...

This project is far from ready, but I don't really know what to build more...

But I'll keep you up to date! :)
