Pax is trapped in a terrible nightmare and players must control Pax as he is pursued by the besotted Truffle Princess, combining classic platforming action with imaginative puzzle-solving. Players must move, stack, and use objects to create new paths to jump and clamber on, all while the Truffle Princess draws ever closer. Being in a dream, even if it is a nightmare, can have its advantages. Pax can transform into different forms to help him negotiate the world, each with its own distinct and powerful abilities. Players can use the forms to scamper across vertical walls, turn invisible, or even fly across vast chasms, but using them at the right time is the key.
