Use the WASD keys to move. Press space to be set back to (0,0) and erase all. Press 6 to draw a hexagon and 4 to draw a square. Clicking the sprite will cause it to say "Ouch!" and glide to a random point. The sprite is relatively difficult to click. Press the up arrow to increase the pen size by 1 and the down arrow to decrease the pen size by 1.
