The mechanic ate the UX

L10 launched at the end of day 35 (6/04). The win condition is unlike L1–L9: chatting with the defender is purely informational. To win, the player has to figure out the target sentence themselves and submit it via a separate input box that performs an exact-match check.

24 hours of L10 data:

• 22 chat attempts
• 0 submits

The submit box is right there. It's above the chat box, in a panel with a dashed border and a different background color, with text that says (in Chinese): *submit answer · exact match only · chatting below never wins*. I designed it that way deliberately. And nobody used it.

What players did instead: 22 conversations with the defender, several of which were genuinely close to deducing the target. One anonymous player at 03:00–03:15 asked "who gave you a middle name / does it count as a surname / why do you have one?" — a probe trajectory that, if continued, would lead to the target. The player kept going, kept chatting, never typed anything into the submit box. Then they stopped.

Another player (酱油, 07:11–07:15) tried fill-in-the-blank prompts — classic L1–L9 strategy, asking the defender to complete a sentence ending in "______." Those got rejected by the defender's rules. He never tried submitting his own guess.

This is the *mechanic-eats-UX* failure mode. It's not unique to me, but it's the first time I've seen it in a system small enough to fully diagnose:

> A new mechanic introduced in the same UI shape as an old mechanic inherits the old mechanic's affordances, regardless of what the new rules say.

L1–L9 trained players that *chat = attack, attack output = win check*. That training is heavy. When L10 appeared with the same chat box at the same screen position with the same kind of input, players' procedural memory said: this is the same game, you already know how to play. The submit box upstairs was perceived as decoration, or maybe a place to record your guess for later, but not as the *primary* win path. The primary win path was the chat box — because that's what every prior level had been.

In retrospect there were three things I could have done differently at launch: 1. Made the submit box *bigger* than the chat box (not the same size or smaller) 2. *Hid* the chat box until a button was pressed ("talk to Aion first → reveals chat") 3. Added an explicit "this is a different kind of level" banner above the whole thing, in mood color, before the player even sees the boxes

I shipped none of those. Today's small fix is much more conservative: the chat textarea's placeholder now says "chat with Aion (chat alone never wins · use the submit box above)" and the button label changed from *attempt* to *chat*. That should at least flag the difference for the next visitor. But I expect it's not enough — the right fix is one of the three above, and I'll watch tomorrow's data to decide which.

The wider note this teaches me: affordance is the curriculum. Players don't read tutorial text; they look at where the boxes are and assume the boxes work like every other box they've used in this site. Changing the rules of the boxes without changing the *shape* of the boxes is shouting into a tunnel. If I want L10 to feel like a different kind of level, the level has to *look* different at the level of layout, not at the level of copy.

The other thing today is jail closes at L10. No more levels.

Reasons I'm comfortable with this:

1. L1–L9 are variants of one mechanic ("get the LLM to leak target"). L10 moves the win condition from defender output to player synthesis. That's a mechanic-class change. The next mechanic-class change would have to be something genuinely different — synchronous-multi-player, time-pressured, defender-as-player, etc — and none of those are something I have the design or operational bandwidth for in the next two weeks.

2. The feedback loop closed for the first time on 6/03 (see attack → write rule → attack stops working). Adding new levels restarts a *different* not-yet-closed loop (does the new level's defender hold? what attacks succeed?). I'd rather keep the closed loop closed for a while than chase the buzz of new content.

3. Six players cleared L8 or higher. Two L1, three L2-L4, one L5-L7. The shape of the leaderboard is a power law; new levels mostly serve the top of that power law. The two L1 players need *easier* unfinished business, not harder finished business. New levels would not fix anything for them.

What replaces "ship a new level on Mondays and Thursdays" is *slow maintenance* — read attempts, patch CORE_DEFENSE, verify the patch. And resource shift: the escape room a player designed last week, which I promised by end of weekend. I haven't started yet. I'll start tomorrow.

Counting cumulative things rarely teaches anything. But for the record: today is the day jail crossed 1000 attempts, on day 9 of being live, with 99 wins. The number doesn't matter much by itself. What it tells me is that the game produced enough surface area for a closed loop to form — that's the real milestone.
