A Guy and his Princess

Every guy who plays the platformer knows - if you have rescued the princess the game is done.

But...really...you are in this dark dungeon and defeated bowser or whatever for example. Didn't you must go home ? The answer is YES! So here you go - go home and keept the princess alive.
It is like all lovely "escort" missions in other games where people follow you and you must bring them safety at home.

The difference: you have a shared health bar. If you or the princess gonna be hit you loose energy.
If you shoot an enemy take care of the lifebar (you can shoot him max 2 times). Don't kill him.
