Solve the riddle to save yourself, and save the Garonne!

Captain Flaggy of the Torment Barge is missing! The barge is in the dark, seems to have been damaged and searched, and access to the rudder is impossible! In 25 minutes, the tide will reverse and rise. The barge will then be propelled towards the Pont de Pierre de Bordeaux. If you fail to reach the rudder room, you will crash on the deck and all the chemicals in the barge will spill into the Garonne! You also need to find out why the captain disappeared.
This Ecape Game is proposed by the association «Water Family, du Flocan à la Vague» with the support of L'Eau Bordeaux Métropole.
