Emoticube

Emoticube is one of Mona's microgames in WarioWare: D.I.Y. Its name is a portmanteau of "emoticon" and "cube".

Gameplay
The goal of the game is to stop the cube at the smiling face. To do that, the player has to watch the cube carefully and tap the Stop button when the smiling face appears. If another face is selected other than the happy face, the game ends in a loss.
