For some reason, a lot of people got stuck on this level, even though I thought it would be an easy one. There was a note near the sign with the first three digits written on it, and you had to figure out the fourth one.
Ah, I intentionally didn’t make it stand out too much, so there would at least be some challenge in finding it :) I thought it would be too easy if I put it right in front of the player. Oh well, we live and learn :)
