Der Fluch des Ra [The Curse of Ra]

It's the year 1924. As a discoverer, you came across an ancient Egyptian tomb that you, of course, immediately entered out of your curiosity. Unfortunately, the stone door has closed behind you with an ominous rumble and you now seek a way out of the chambers full of treasure. In 60 minutes you will be out of breath and seem to have enraged an uncanny force with your intrusion. Can you find the clues and solve all the puzzles?
