Prism Relay — Game guide

Your goal

Reach the finish of 24 floating courses while steering freely sideways. Every jump changes your color. Three optional light crystals reward careful exploration, and a midpoint checkpoint helps you recover.

Tips to try

  • Use the slower pace with S while learning a difficult gap.
  • Line up with a crystal before takeoff; forward movement continues in the air.

Questions about the game

Why did I fall through a platform?

Only neutral platforms or your current color support you. Jumping swaps cyan and amber.

What changes at later checkpoints?

From level 13, cyan at the checkpoint opens the left relay bridge; amber opens the right.
