Spelunky

In the game, there are three characters you can save… a blonde male, a dog and this blonde chick.

The player can encounter damsels in distress trapped in the caves, who can be picked up and carried to an exit. Successfully doing so returns health to the player. It's possible to unlock the damsel as a playable character; gameplay is identical, except that the player encounters spelunkers to rescue. Another unlockable character is the "Tunnel Man", who possesses a mattock instead of a whip.
