Animal Hacks is a great arcade-style game where you use the keyboard and mouse to operate your character. For example, when your character jumps in the air, press the space bar to jump. The keyboard is used for movement and some additional functions like zooming or moving on by clicking on the X and the Y keys. If you are holding down Control, your character will change its appearance and some actions will be repeated when you use the arrow keys and the space bar. There are also some extra actions that need to be completed before moving on to the next level.
