I tried to record this, but couldn't get any further than opening up all the rooms on the second floor. Couldn't get the second door in the "demonology" book room to open up. Couldn't find a key anywhere. Searched everywhere that opened, ran around the house multiple times, nothing triggered...so I gave up.
All I saw was essentially a house with bad electrical wiring and 2 keys that opened doors. It wasn't anything else. Not very fun, to be frank.
