INSTRUCTION
The game is to control a particle to jump through a cosmic tunnel that consists of halos. If the player strikes the xylophone when the particle reaches the center of the halo, it will leap upward. If the player strikes around the xylophone, the particle releases a wave that triggers multiple halos to resonate and rise higher. The particle would evolve into different forms as it reaches a higher level. Are you able to launch it into the deep universe?
