It's an educational "blowing" multiplayer 2D game based on Phidgets. For the gameplay, two players need to collaborate with each other. One player pushes the force sensor to make the star shoot at different initial speeds. When the star is flying into the sky, each player controls one of the horizontal speeds of the shooting star based on the IR-reflective 10cm sensor in order to make the starlight at the specific positions in the sky to achieve a constellation.
