Thanks! It took about 3 weeks total (I had a lot of free time) to brainstorm, make each puzzle, and piece them all together. All the passwords and other puzzles use timers, events, and other blocks which you can see in the control panel categorized by letter. For details you can look into all their setup actions. Specifically I also published the 4 digit code lock blueprint that explains how it works in the description.

Played it and beat it. Very clever, and must have taken a lot of time to create. Great job, I really enjoyed it! How did you do the passwords?

this is genius

Thanks, I'm glad you enjoyed it

Very nice - enjoyed that escape room
