A thief thieving a thief

A mystical relic has been taken by force from a peaceful people and hidden in a museum. Only a talented thief like you can retrieve this treasure and do the right thing by returning it to its rightful owners. >>> Warning : single player ONLY (multiplayer would break some systems/puzzles) <<< Don't forget that you can zoom in once in "inspection mode", this will allow you to read the texts more easily by enlarging them! I took care to solve as much as possible the sources of potential bugs. If, despite this, you encounter a problem, you can report it on the steam page of the room. Don't hesitate to give feedback on the overall difficulty level of the room or on a particular puzzle, I might update the room to allow choosing the difficulty level. Fire up your brains and have fun!!!
