Quantum Castle

Gordy's small green furry creature, resembling either a goblin or a troll, enters the very castle indicated in the title in order to take possession of the treasures of the dragon living there - but for this he will have to go through many rooms filled ... not enemies, but arithmetic problems for preschool age. From the splash screen one might get the impression that this Gordy only meets us at the gates of the building, but the final video makes it clear that we played for him.
