How do I save the game?

[Schwarze Pest]

Oh this room. With the noose behind the wire and the books. Go to the closed door. On the right side should be a switch or so - use this. On the ground now should come up some colored circles.

Look for the three circles that contain all three colors (blue, yellow, green when i remember) in them and push the barrels on these circles.

Or short: push the barrels on the multi-colored circles.

Sorry for bad english.
