DOS Games Discussion

So, what I remember of the game is that int he middle there was a white face, on the left and on the right there was a pipe-like playfield (mirrored), where you had to prepare a way for a signal to reach the face. Everytime you allowed the signal to reach it the level would be completed and a different type of emotion would be displayed on the face.
It was a puzzle game, and that's all I can think of .
