If the witching hour is three to four, then it logically follows that the clowning hour is midnight to one.

I don't understand the exact mechanism, but it's a result of doing the bathroom sequence before you drop off Mint. You're supposed to be in the flashback cutscene once you exit Mint's room, but the game gets confused and gives you control over the character. That's also why the screen is tinted until the cutscene after Orion, the game still thinks you're in the flashback.

I'm thinking it was an oversight. Looking at all the other spots where the dialogue saying you're going the wrong way pops up, they're all replacing transition spots between rooms. It works fine there since there's no other map tiles to visit, but in the hallway the same behavior doesn't work because you can just walk past. My theory is that there was one event made that was then just copied for every spot.

Awesome! I completed runs for each of the categories below: Secret Ending Any% : Normal Ending All Cards : Secret Ending All Cards : A couple of notes for these runs: I added a censorship bar for the image at the end of the secret run. I don't think it's actually problematic but I'm erring on the side of caution with that. The normal ending all cards run is a bit rough since that was my trial run. A big thanks to GM35 for teaching me about the torso clip to get into the armory, having an excuse to use that trick in a run was honestly my main reason for being interested in an all cards run.

Would anyone else also be interested in additional categories? The most straightforward one I can think of would be adding one for the secret ending with the fool card, which has the benefits of being both quieter and shorter than the standard ending segment. For a more arbitrary challenge option, maybe an all cards mode to contrast with any%, where you need to have all 22 different tarot cards in your inventory when you finish?
