How to Play Klustar
Quick start
Select one player and an easy setting. Move the cluster toward a useful shape, rotate with A/B and complete a square before the structure reaches the screen edges.
Controls
The D-pad moves the cluster in four directions. A rotates clockwise and B counterclockwise around the Magic Block. START begins or pauses the game.
Klustar — About this game
Klustar for Game Boy Color. Think about where the next shape will attach before moving the center. A rotation can complete a square or make another side dangerously wide. Endurance and Countdown provide different pressures, but both reward keeping useful attachment space open.
This entry is a beta build of the game.
