Mixel Worlds has Mixel the cat as the main character. Like all cats, Mixel has only nine lives so be careful not to lose them all. Gathering hearts will help him gain his lives back. Use the W to jump and A and D to move. The arrows work as well for left and right and up to jump. You'll explore a world full of coins and keys you must collect to open the door to the next level. There are many traps to avoid, like spike floors and moles. You can jump on mice to kill them and you'll have to learn how to use the springboards in order to really excel at Mixel Worlds.
