Guys,
How long it took you to escape the room in Puzzled 1-4?
Without reading the Walkthroughs?
Mine as follows:-
Puzzled-1: Unsolved, getting stucked with the suitcase's lock code & gameboy that won't work !!
Puzzled-2: Solved in 20 minutes. Most challenging part, finding the keys hidden near the door edge.
Puzzled-3: Solved in 1 hour plus. Most challenging part, finding the "Datcode" beneath the chair.
Puzzled-4: Solved in 45 minutes. Most challenging part, finding the safebox hidden underneath the OGN poster.
