Hey Meowium99! Thank you so much for trying!
For your information it seems to bee an outdated version. In the current online version, there is an additionnal clue displayed when you click the sword 2 or 3 times (and when you did that à 6:00 ) it did not show up.
Maybe this will make it possible for you to progress even more !
Anyway, thanks again and thanks for your time!
