From the publisher's website:

If a player is left behind, you need to rescue him. Otherwise, you'll all lose! You are a team of adventurers – trapped in a cursed temple. Together you must activate the magic gems in the temple chambers in order to banish the curse. Look out for one another. Some tasks can be accomplished only as a team – and you have only 10 minutes before the temple collapses! Escape is a cooperative real-time game, that is not played in rounds. Instead, each player rolls as quickly and as often as he can with his five dice. The dice determine your fate. Discover the different temple chambers by rolling the correct dice combinations. Take care, though, because if you fall under the spell of the Black Mask, you‘ll need the help of the Golden Mask and your team-mates in order to keep moving! Act together. If several adventurers are together in one chamber, you'll activate more magic gems faster! Two modules make Escape even more exciting: The modules “Curses” and “Treasures“ make gameplay even more varied. The treasures aid you whereas the curses make escape more difficult. After all, an adventurer who is unable to talk or who must roll his dice with one hand stuck on top of his head will have a tough time working with his team! The 10-minute soundtrack enhances the exciting atmosphere of the temple adventure!
