The limitation is a special condition that your game must follow, but is open to interpretation. If you are unsure if your idea doesn't fit the limitation  just remember that everyone will interpret it differently.

The limitation is: You are your own ammo

This limitation is pretty open to interpretation. Maybe you fire off a little bit of yourself as a projectile, or maybe your health and ammo are tied together. It's up to you! 

Q: How do I know if I Incorporated this limitation enough?
A: There should be a clear tie between the player and the ammo. 

Q: What if I don't want my game to have shooting?
A: Ammo can generally be substituted for some other expendable resource.
