Audio Pen transforms sound into sight. To use, shout into the microphone to clear, and talk into the microphone to set the size. Use left and right arrow keys to change color. Use W and S to hide or show the cat, and A and D to show some animals to color in. Press Q and E to change the shade of color. Click to draw. If you do not have a microphone, press space and use up and down arrow keys to change the size, but the microphone version is way better.
Credit to @PaulRHJT for music. In case your wondering, I made the sprite by combining Pico, Scratch cat, a Pencil, and a bent line.
