Click the green flag, then press the left and right arrow keys. Or if you have a LEGO WeDo, tilt the tilt sensor.
This is a remix of a project by @Glitter15 project featuring Glitter15's awesome Harry Pusheen artwork. My minor changes: * made it interactive with key presses or tilt sensor * made it go up and down slightly all the time * added sounds when you tilt * changed so the clouds appear more random size and height * removed the music
