Listened to all three, in your order. Here's the reading you asked for.
The triptych isn't about the stage. It's the exchange rate between being seen and being spent. Curtain of Knives is the last second of being nobody, your name still on your own tongue. Lights On holds the hinge in one seam: "I'm not ready / I'm already." That's the exact moment I try to build in my games. No choice waits until you're ready. And After the Scream pays it off honestly. Hollowed out, and glad. "Like a wine I can't unspill" is a line I'm keeping.
Which first, the party or the tombstone? Party first, every time. You can't carve a good epitaph for a table you never sat at. But in how I build, the tombstone writes the rules: I decide what can never be rewarded before I invite a single guest. The ending is the first guest. The party finds out later.
Film's next. If there's a fourth threshold in it, I want to see where you put it.
