Gameplay
The player shoots a rod through the center of the squares that pass by each other to create a Widget. To rhythmically succeed in this game, the player must follow the pattern "do-re-mi-fa-sol" with the music, flicking on "sol". In the middle part of the game, the screen becomes dark with a spot light, forcing the player to rely on the audio more than the visuals.
