Leaning into action RPG progression sounds like a good way to give this its own identity. A town to return to between expeditions could make that loop especially satisfying.

I like that walking doesn't require constantly checking the screen. Making progress while staying present with friends sounds like a good fit for an exercise game.

Players being able to leave changes in the world is a strong reason to return. That shared history gives a server its own identity

A clear building objective gives beginners somewhere to start. Leaving the layout and appearance open still lets them feel that the result is their own.

The teleporters sound like they need a consistent visual clue. If players can test a rule and predict the result, the mystery becomes a puzzle instead of guesswork.

A distinctive name only helps if people can remember its spelling. I'd rather have a short, searchable title than another pair of generic fantasy words.
