At the end of each quest you'll find a magic key. Take it and use a portal to access to the next Quest.
When you complete all the Quests you can write on the magic billboard at the spawn point.
The focus is on the quests so everything else is pretty basic: only a few mods and additions to spice up the game, not much else to do.
The areas around the quests are all protected, so if you want to build you have to move a bit far away.
The quests are:
- Floating Islands
- Ice labyrinth
- Asgard
- Seaside
- Space Station
