Pressing the right arrow once will send the crazy horse head at a fast speed to its right. Pressing left arrow once makes it go slower to its left. Press both left and right to stop the horse. Use the number keys, 1-9 to change background and music. When using the left arrow, it glitches, but it just makes it crazier. Space key to stop music Press "s" for seizure mode.
All credits to KatKraze. I just made it weirder.
