"3 inside the arrow" puzzle stole my money, ate my firstborn and put bedbugs into my sofa.
Really cool rule-discovery game!
I think it is a trial and error puzzle, they are relatively common
You build up a right sequence step by step
or i missed the clue too :]
hi! hadn`t completed the game yet, but there is a (probably) glitch with the 4-digit code safe. If you click the numbers fast enough, they will stop for a moment at the right number, so you can easily open it without knowing code at all
