Let's Play Weird And Unfortunate Things Are Happening - 16 - Flying Eyeball Centipede
I'm dearly hoping that we're going to run into another Fool at some point, because otherwise putting four things that need a Fool Key to unlock at this point in the game is not a move I particularly like.
In the first half of the game (where all of the Fool Keys came from), there was, roughly speaking, one Fool per major area and one Box per major area, which felt like it was setting the boxes up as an extension of the Fool Rooms. You found the room, navigated through it, and then had to find another hidden thing to get more cool goodies. If it turns out that HALF of the Boxes are at the end of the game, after a naive player like myself would've spent them all? That's just dirty pool.
I'll keep my eyes pealed, though. Maybe there are more Keys hanging around somewhere, and I've just missed them... like a Fool.
