I looked at it but it seems impossible to actually input the combinaison. No matter what i do i either get locked with the second valve or can't use the third at the end. Any tipps ?
That's weird, i would have to test myself i can't really remember to be honest. I don't have the time right now so... but I know the valves are like this:
-First one you can reach is the number 3. -The second you unlock is the number 1 -The last one is the number 2.
