The primary objective is to collect "Time Pieces", 40 of which can be found in the game, which unlock additional levels as more are collected.[13] After being defeated, the enemies drop "Pons", currency that can be used to unlock additional challenges and purchase badges that increase Hat Kid's abilities.[14] The player can collect Yarn Balls in each level, which can be stitched into new hats to wear. Each hat grants Hat Kid a different ability, such as a faster sprint or brewing explosive potions. Other collectibles include "Relics", which can be used to unlock "Time Rift" bonus levels, and "Rift Tokens", which can be exchanged at a machine for bonus materials such as music remixes and additional cosmetics.
