Kurupoto is a puzzle game that involves manipulating the environment to make a smiling yellow ball fall into a ring. Each of the game's 100+ stages features a fixed arrangement of cubes that rotate 90º with every stylus tap. Also found within a stage are "aliens" that alter the ball's movement. The ball is described as a star and the rings are considered halos, the source of a star's "power." The single-player Story Mode helps explain the stars' origin, as players unlock new puzzles while advancing across a series of constellations. Normal Mode has players trying to beat each stage's high score to unlock a bevy of bonus images.
