Got a full playthrough here without commentary and with both the endings. I had no idea how to open the secret door or what time you get the extra mode though sadly (maybe it's something to do with the cat poster).
Thanks for sharing your King's Comfort experience! We've added it to our Youtube playlist. I'm still catching up on a few of the latest streams, I look forward to checking out yours!
Kaleb made a post in the Devlog giving some hints on how to access the secret mode and secret room. Check that out and I'm sure you'll be a few steps closer to figuring out how to access these hidden features.
