What you got could actually be another cypher! Idk how exactly did you get it, but it is much more organised now. It also looks like an end part of some URL.
I'm gonna try and find out more about it, but I also think, that we won't get much out of it before the full game comes out.
P.S I think that in the cypher it's most definetly not a 6 but a 5 (, I've made a recording, looked carefully and it looks like it's just the fire animation that makes it look like 6,) and case matters, so it is M in Mondays and not m. So, could you try that with l-S5Sgq2?2-Mondays instead?
