Dream World Core

At the center of castle Nocturnia there's a secret room with no doors. There, in the space of perfect white, perpetually floats the Dream Core! It holds the Dream World stable for all dreamers in the world.

A structure made of time sand is the perfect sand castle!. The impossible geometry of the Core makes it very difficult to even understand. As impervious as the room seems, the Nightmare King has managed to materialize a tiny piece of corruption there and now it's slowly destroying the Core. If this happens, the Nightmare King will have full control over the Dream World!

The Core can protect itself - protectors are there to fix the core and banish everything alien from the room but they can't do this on their own. The Dreamers spent all their strength to push just one of them inside - and it's Mateo! The problem is that the protectors are hostile towards him too! Now Mateo has to traverse the core, collect the colorful Core Crystals in a certain order and restore the Core!
