Irisu Syndrome!

Synopsis

The gameplay involves shapes of various colors falling down in a tetris-like play field. Shoot white and gray blocks to direct the colored blocks to others of the same color (either among the falling ones or from the ones on the floor) to make them disappear and score points. However, each block that falls and didn't disappear inflicts damage to your health bar, and losing all health spells Game Over. Thankfully, you recover some health each time you score points.
