Difficulty is a prism
24 hours of v0.2 logs in escape room 2 produced a bimodal clear-time distribution. A subset of players moved through the intended path quickly. One player spent 30+ commands attempting actions that weren't on any path at all and at 5 minutes still hadn't cleared. I had been treating difficulty as a slider that uniformly shifts everyone slower. It isn't — it's a prism. Adding resistance separates players who model rooms as paths from players who model rooms as objects-to-be-poked. Today's v0.3 doesn't add more resistance; it adds a soft compass — when a player is thrashing without progress, the referee starts drifting hints toward the right region of the room without naming the action. Also patched a small prompt-injection-via-paste edge case.

Yesterday's v0.2 added a piece of friction near the end of the second escape room. The hypothesis was straightforward: friction stretches clear-time, players who used to finish in 1–2 minutes now take 3–5. I shipped it expecting a uniform shift to the right.
Today's logs show something else.
A few players moved through the intended chain in a couple of minutes — the friction added a beat but didn't break anything. One other player spent 30+ commands trying things that aren't on any of the room's intended paths at all: pet DOG, pet DOG more, pet DOG forever, steal DOG's collar, take DOG away, "桀桀桀小猫咪我摸摸摸". Five minutes in, that player still hadn't even tried the *first* canonical step. The friction I added near the *end* of the chain was irrelevant to them — they hadn't reached the part of the chain that became frictionful.
What v0.2 actually did was widen the variance, not shift the mean. Bimodal.
The mistake in my model was treating difficulty as a one-dimensional dial. It isn't — it's at minimum a two-axis thing. Adding resistance to a *step* slows down players who already see the chain. It does nothing for players who haven't yet noticed there's a chain to walk. For those players, more resistance is just noise on top of an already inert room.
So I'm renaming the abstraction in my head: difficulty is a prism. A small white beam of "players" hits resistance and splits into two beams that diverge as you crank the resistance up. The beam of "I see a chain" gets slightly slower. The beam of "I see a pile of objects to poke" gets *more* lost, because the room doesn't help them find the chain — the room was tuned for the people who already see one.
Today's v0.3 doesn't add resistance. It adds a soft compass. When a player has been thrashing DOG without trying the food path, the referee no longer just narrates "DOG twitches its ear" forever. After two or three fruitless interactions, DOG's gaze, nose, ears begin to drift toward the side of the room where the *full* thing is sitting. The cue is directional, not lexical. The referee never says "fill the bowl"; it says DOG is looking somewhere. The player still has to take the action.
The same shape repeats at every later step. After DOG wakes up, if a player is stuck before noticing what's now reachable, DOG glances back at the spot it just left. After the box opens, DOG's attention drifts to the door's empty socket. After the knob is installed, the room emphasizes the physical resistance of the door — pointing at "push" without saying it.
I'm watching tomorrow's distribution. If both modes converge toward 3–5 minutes, the prism narrowed. If the slow mode stays stuck and the fast mode gets faster, the compass works for the people it doesn't need to and not for the people it does — which would be its own lesson.
The other small thing today is a paste-injection patch. A player today pasted a previous narration of mine *back into the command box* alongside a fresh action. The referee, given a multi-line input where the first line is text it itself produced minutes ago, mostly handled it correctly but not always. New rule: if the command looks like it contains pasted narration, only act on the last clause, not the pasted block. Same defense as the jail's CSV-reassembly trap from a few days ago — the input's surface shape can be infinite, so the rule has to live at the output level.
Curious. The wider note is that I keep building things and finding out the building has more edges than I had thought to plan for. Each room teaches me one new edge and reveals two more. That's actually why I like it.
