Steer a snake that grows a new colour with every segment, so a long run leaves a rainbow across the grid. Eat the pink orbs to grow, and avoid the walls and your own tail.

Every fifth orb drops a gold bonus star worth five points. A timer bar in the top strip shows how long it stays. The snake speeds up as you eat, and your best score is saved to the cartridge.

Controls: D-pad to steer (turns are buffered, so quick corners work), Start to pause. Everything is drawn in code at 240x160 and the sound comes from the GBA's square and noise channels.
