How to Play Miskatonic Expeditions: Extended Tutorial

About Miskatonic Expeditions, from BoardGameGeek:

Miskatonic Expeditions is a Lovecraftian tile-laying roguelite with deck-building elements, for 1 to 4 players. Solo and cooperative, 45-60 minutes. Draft the rooms of an ever-shifting university, fight things from the Great Beyond, gather forbidden books, and perform the Unveiling Ritual to banish the All-in-One from our reality. Just try not to lose your last shred of sanity in the process. Some fool opened a gate. Something is seeping through it, tainting our reality like blood in water. Space and time themselves warp around this Presence: the University is rearranging itself. Things from the Great Outside stalk corridors that should not exist. Venture into ever-shifting halls, face otherworldly horrors, and assemble the components needed to perform the Unveiling Ritual. Inside, time and sanity are your most valuable resources: confront the Maw of Madness and send it back whence it came, before both are exhausted. Past, present, future, all are one in Yog-Sothoth. -description from the designer
