Cool Cool Jam is an action-packed adventure that whisks players away to a world of vibrant colours and infectious tunes. In this unique rhythm-based game, two young protagonists - Wave or Midi - find themselves transported 1000 years into the future, landing in the charming town of Musey Town. There, they're told by bass guitarist Lan-K that their only hope for returning home lies in becoming a musical sensation and impressing the enigmatic Jazzy Egg. With just one week to form a band and achieve this goal, players must navigate the town's diverse districts, each with its own distinct theme and music style.
As players explore Musey Town, they'll encounter colourful characters and challenging mini-games that require precise timing and rhythm. By successfully completing these mini-games, they'll win the attention of the locals, progressing the story and unlocking new opportunities. The game also features competitive multiplayer modes, where players can challenge each other or the CPU to play iconic tunes on a range of virtual instruments.
