You are the black hat, and use the arrow keys to move. Run away from the milks, but you can kill the milks that are not golden with your flames. When invincible time left turns to 5, you can press space and turn in to a potato-eyed horse that is invincible. The invincible time left is how much longer you can be the potato-eyed horse. The golden milk cannot be killed so just stay away from it.
Thanks to Mikhail for the idea.
