A 3D platformer with varied gameplay and a lot of collecting. The structure is roughly hub-and-spokes with a handful of areas each containing several levels. The main collectible (“time pieces”) unlocks new areas at a brisk pace (the final boss is unlocked at 25 out of 40 time pieces). Side collectibles include yarn (which allows for the creation of new hats with new abilities), a currency called “pons” (which can be spent on badges that enhance or modify your abilities in various ways), and new skins and color schemes for the hats and the player character.
