# Language Design Evidence
-
**Status.** A bounded evidence check of two shipped language-decipherment games against the team's language-play proposals. Sources are developer statements in official material and interviews; secondary summaries did not fill gaps. Nothing here shows that our version will be fun, readable or long enough. Three kinds of claim are kept apart: an implemented mechanic the developer describes, a stated intention, and empirical evidence from players. Neither game's sources supplied the third beyond developer impressions.

**Status.** A bounded evidence check of two shipped language-decipherment games against the team's language-play proposals. Sources are developer statements in official material, interviews and one developer-authored article; secondary summaries did not fill gaps. Nothing here shows that our version will be fun, readable or long enough. Four kinds of claim are kept apart: an implemented mechanic the developer describes, a stated intention, evidence the developer reports from players, and our own proposals. Neither game's sources supply player data beyond the developers' reports.
## Heaven's Vault (inkle, 2019)

**Implemented, as the developers describe it.** Inscriptions are broken into words and the player selects, for each word, from a small set of English candidates the player character offers; words are built from smaller "atoms", so related symbols hint at connections already made (Game Developer; inkle page). The game never says whether a choice is right: "What we don't tell you is if you're right" (Ingold, MCV). A guess is fed back into the story and into later translations, and a wrong idea "can feed into the narrative" (Ingold, MCV). There is no fail state; the design "encourages correct interpretations or eliminates options" as a player drifts (Game Developer paraphrase). Inscriptions are generated to match each player's dictionary progress and location (Game Developer). Ingold expects players to be confident about roughly a third of the language by the end (TheSixthAxis). The player still decides which candidate to commit, whether to trust an earlier guess when a word recurs, and what a place therefore is; the companion's hinting role is not described in these sources.

The game never states whether a choice is right: "What we don't tell you is if you're right" (Ingold, MCV). Progress does not wait for a correct translation, but a choice has consequences: a wrong idea feeds into the story and into later translations (Ingold, MCV), "the wrong translation might send you down the wrong track" (inkle page), and as a player drifts the design narrows or eliminates candidate options (Game Developer paraphrase). Inscriptions are generated to suit each player's dictionary progress and location (Game Developer). Ingold expects players to be confident about roughly a third of the language by the end (TheSixthAxis). The player still decides which candidate to commit, whether to trust an earlier guess when a word recurs, and what a place therefore is. The exact rule by which a guess becomes a settled dictionary entry, and the companion's hinting role, are not described in these sources.

**Stated intention.** To feel like translating rather than to model a language: the "Guitar Hero of linguistics" (Humfrey, Game Developer); ownership through uncertainty (Ingold, TheSixthAxis).

**Empirical evidence.** Only a developer impression that guesses are "usually pretty good" (MCV paraphrase). No published player data.

**Transfer limit.** The uncertainty works because a story absorbs any guess at no cost and without a clock. In Hold The Horde a reading is spent under oxygen and horde pressure and can fail physically, and a fixed station cannot generate inscriptions to fit progress; placed redundancy must do what inkle's generation does.
+
**Transfer limit.** Heaven's Vault's consequences are narrative and arrive later through story and further inscriptions. In our game a reading can be applied in the world at once, under oxygen and horde pressure, while journal reading is paused; a wrong reading can cost supply as well as understanding. Fixed geometry limits regenerating placed inscriptions to fit progress, though adaptive selection of which persistent clues a player meets remains possible if established clues stay coherent.

**Implemented, as the developer describes it.** A redundancy rule: "every word you encounter in the game must be seen at least twice in two different situations" (Moya, Game Developer). Players are not expected to understand a word at once; they "jot down a few hypotheses and keep exploring" in a notebook (Moya; store text: "note each symbol, keep track of your surroundings"). Two systems are named but not explained in the reachable sources: an "Obra Dinn-inspired validation system" and "automatic translation of complete sentences" (Moya, Game Developer). The widely reported picture-page batch confirmation could not be verified from a developer source within the cap and is treated as unverified. Context comes from people speaking and acting.

**Implemented, as the developer describes it.** A redundancy rule per word: "every word you encounter in the game must be seen at least twice in two different situations" (Moya, Game Developer), usually more. Players are not expected to understand a word at once; they "jot down a few hypotheses and keep exploring" in a notebook (Moya; store text: "note each symbol, keep track of your surroundings"). Words are introduced from the concrete and simple toward the abstract, in an order set by gameplay and staging (Deep Dive). Two systems are named but not explained in the reachable sources: an "Obra Dinn-inspired validation system" and "automatic translation of complete sentences" (Moya, Game Developer). The widely reported picture-page batch confirmation could not be verified from a developer source and is treated as unverified.
-
**Stated intention.** "The feeling of the traveler who explores countries where he or she doesn't speak the language" and understands "through cultural immersion and practice"; "confronting the player with seemingly impossible challenges while discreetly giving them all the tools and clues they need" (Moya, Game Developer).

**Empirical evidence.** None in the sources; the systems emerged from development trial and error, not reported player data.
+
**Reported evidence.** Moya reports "a lot of playtesting", that some words or sections "were definitely too difficult", and that the fix was to "add a few occurrences, a few clues, an additional place or character" using the word in a new context; the result, in his account, was levels that "could be completed by just about anyone" (Game Developer). This is qualitative and developer-reported, with no public dataset and no causal proof for our game.

**Transfer limit.** Sennaar's context is living speakers in safe spaces. Our languages have no speakers, and observation costs oxygen. A batch-validation system also grants a certainty our proposals deliberately withhold; adopting one is an explicit change of stance, not a detail.

**Transfer limit.** Sennaar's context is largely conversation with living speakers; our proposals have no living speakers of the alien languages, but they do have survivors whose testimony and labels supply context, and whether Sennaar's observation is ever under pressure is not established by these sources. A batch-validation system also grants a certainty our proposals withhold; adopting one is an explicit change of stance, not a detail.
## What this says about the released positions
-
**"Every inference testable", "costs little", "cannot be solved by dialogue".** Heaven's Vault is a working design in which inferences are not testable at all; the story absorbs them. Testability is a preference that presumes a machine response for every sign; no source supports it as a requirement. "Costs little" is contradicted by the mechanic taking inkle "about a year and a half" (Ingold, MCV) and Rundisc "extensive trial-and-error": the interface and consistency are the cost, not the instances.
+
**"Every inference testable", "costs little", "cannot be solved by dialogue".** Heaven's Vault never states correctness, yet wrong guesses surface through later inscriptions and story consequences, so testing need not mean a machine responding: text, context and testimony test a reading too. "Costs little" is unsupported; inkle's "about a year and a half" for the mechanic (Ingold, MCV) and Rundisc's iteration signal burden without measuring ours.
-
**"Any two comparable instances plus one that breaks the reading will do."** Sennaar's stated safeguard is a per-word rule of at least two situations, and Heaven's Vault compensates for misses by generation. Neither shows that two-plus-one guarantees recovery, which still depends on the player noticing the exception. Context-dependent signs also still yield reusable rules: inkle's atoms are precisely reusable context, so an indexical language does not exclude a lookup.

**"Any two comparable instances plus one that breaks the reading will do."** Sennaar's stated safeguard is a per-word rule of at least two situations, tuned by adding occurrences where players struggled, and Heaven's Vault compensates for misses by generation. Neither shows that two-plus-one guarantees recovery, which still depends on the player noticing the exception. Context-dependent signs also still yield reusable rules: inkle's atoms are precisely reusable context, so an indexical language does not exclude a lookup.
-
**"A hint, match or confirmed gloss removes interpretation."** Heaven's Vault hands the player candidate words for every inscription and still leaves choice and consequence; Sennaar's automatic sentence translation is assistance the developer describes as part of the puzzle, not its removal. Help does not by itself dissolve interpretation, and required help is a gate only where a policy makes it one.

One inherited example should be dropped: a ledger tally matching the player's death count assumes a count-based mechanism no direction has adopted.
## Design implication and the open choice
-
Both shipped designs give the player something firmer than open inference: candidates to choose among, or validation once enough is consistent. Both survive missed clues by redundancy or generation. In a fixed station priced in oxygen, the transferable safeguard is a stated per-sign redundancy rule, and the paused journal can present a sign's own recorded instances side by side without confirming a meaning. The choice the sources cannot make for us: withhold confirmation entirely and let readings feed consequences, or confirm in batches once enough is consistent. The first fits discovery first and personal ownership; the second gives certainty and pacing. Neither source shows which holds up when reading is done under threat.

Both shipped designs give the player something firmer than open inference, candidates to choose among or validation once enough is consistent, and both survive missed clues by redundancy or generation. The transferable safeguard for a station priced in oxygen is a stated redundancy rule per learnable unit, taking Sennaar's per-word rule as precedent rather than a validated minimum, with adaptive selection of persistent clues where coherence allows; the paused journal can present a sign's own recorded instances side by side without confirming a meaning. The choice the sources cannot make for us: withhold correctness entirely and let readings feed consequences, or confirm bounded outcomes once observed. The first fits discovery first and personal ownership; the second gives certainty and pacing. Neither source shows which holds up when reading is applied under threat.
