You can use WASD, or Arrow Keys. It can move up, down, left, right, everywhere! Unfortunately, it can also go into the red. I would fix it, but it's cute to have the black dot zoom around the toy. Enjoy! :D :D :D :D
A fun classic toy that's been played with for ages! I don't know who made it, but they'd be the only credit here. Also, my grandparents for giving me a mini Etch-A-Sketch.
