A narrative investigation game for PC where the player reconstructs disputed histories through evidence — with Goiânia and the Cerrado shaping the case.

A playable development build focused on investigation and evidence.

The public itch.io demo is now listed as version 0.93 RC for Windows x86_64 and remains in active development. For the correct files and current installation instructions, please follow the official itch.io game page. This is not a final release; complete human Windows validation is still pending.

Play the demo or support Ecos do Cerrado.

Public demo 0.93 RC is available for free on itch.io. Contributions in USD remain optional and are never required to download. Check the itch.io page for current installation files.

Positioned within a recognizable investigation and narrative-puzzle audience.

Ecos do Cerrado is being developed for PC within the investigation, mystery and narrative-puzzle space. The references below are useful audience and interaction comparisons; they are not claims of equivalence, endorsement or affiliation.

International positioning starts with the player action — inspect, compare, deduce and interpret — while Goiânia and the Cerrado provide the specific cultural and visual identity that distinguishes Ecos do Cerrado.

The public demo demonstrates the core experience; selected assets remain development-stage placeholders.

The current build was produced under independent funding constraints. AI-assisted voice and translation are disclosed as development tools and are not presented as the intended final production standard.

PT-BR and English are the current base language path. Additional languages remain funding- and market-dependent. Release-quality work also includes external QA, accessibility review, audio and presentation polish, and store and release preparation.

Where the right partner could help move Ecos do Cerrado forward.

The current future PC-completion planning figure is US$35,000, including the previously defined US$8,000 first milestone. It is a production-planning base case, not a term sheet, and excludes historical unpaid development. A partnership could combine capital, services or both while preserving narrative control and IP.

The US$8,000 first milestone is part of the US$35,000 total, not additional. The base case covers future PC completion; historical unpaid development, console ports, languages beyond PT-BR/English and major scope expansion remain outside the base case.

Open first. Support later if the material earns it.

Instead of asking for money for a promise, Ecos puts three complete digital companions in your hands before the decision. They are printable, non-canonical companions and never hide content required to play.

Current model: value first, payment second. Support links live inside each delivery. If you prefer to simply contribute without a companion, direct US$5 support remains available.

CHARACTER DOSSIER

Who writes the Diaries

Before N.’s Notebook and Clarisse’s Diary, meet two minds, two bodies and two adult ways of moving through Goiânia.

NONOLHO ZEUS

Nonolho Zeus

Veteran investigative journalist · street reporter · documentary noir

Thirty-two years of reporting left him with one incurable habit: distrusting the first version, including his own. Nonolho separates fact, impression, convenient narrative and missing piece. He is tired of manufactured urgency, adjectives standing in for evidence and sentences too elegant to survive reporting. He keeps going because some facts still deserve to be rescued from noise.

Age52BornJan 17, 1974SignCapricornBaseGoiânia · GoiásProfessionInvestigative journalistExperience32 years reportingHeight1.79 mRhythmlate shifts, deadlines and cold coffee

Peculiar mind

Skeptical, methodical, self-doubting and dryly funny. The moment he realizes he has fallen in love with an explanation, he treats that as a warning sign.

Habits

He rewrites bad headlines in his head, counts recurrences before calling something a pattern, returns to the dullest detail after building a theory and trusts things less when they look too clean.

Desire & intimacy

Nonolho did not turn to stone; he simply learned to hide what he feels more efficiently. Desire, for him, is less conquest than the need to lower his guard for a few minutes. He values closeness that asks for no official version: skin, scent, shared silence, someone who can stay without interrogating him. Sex exists in his life as a suspension of the shift — a rare space where he does not have to check sources, weigh every word or plan the exit. That frightens him more than he admits. Solitude is easier to manage than being truly known.

“If the sentence closes better than the facts, I cut the sentence.”

CLARISSE FERRAZ

Clarisse Ferraz

Documentary researcher · context analyst · field observer · diarist

Clarisse is the archive’s synthesizing intelligence. She reads provenance, chronology, language, omission and contradiction before accepting any version as stable. Her intuition is fast, but she never mistakes it for proof: she cross-checks sources, tests competing hypotheses and notices when a narrative is trying to steer the reader. She is an adult, feminine and autonomous woman; her private life exists, but it never defines or diminishes her intellectual force.

Intelligence

Strong memory for detail, a fine ear for language and an unusual ability to spot inconsistencies. Clarisse can hold two competing hypotheses at once without falling in love with either too early.

Method

She compares origin, date, context, wording and what the record leaves out. She knows silence can be data, but it becomes an argument only when evidence supports it. Intuition opens paths; evidence decides how far she goes.

Desire & intimacy

Clarisse treats desire as part of her autonomy, not as a measure of her worth. She may want sex, touch, conversation or distance, and she knows the difference between wanting and owing, attraction and surrender. Good intimacy, to her, is a place where she does not have to make herself less intelligent to fit inside someone else’s desire. She wants to be seen whole — quick mind, body, humor, ambition, fear and pleasure. What attracts her is not being chosen; it is being able to choose without disappearing inside the choice.

Presence

Dark wavy hair, dark-framed glasses, a sober posture and an attention that is difficult to fool. She usually notices first and speaks later.

“Intuition opens the door. Evidence decides whether I walk through.”

Read the project before opening the build.

Version boundary: the Visual Book documents the isolated 0.9.2 RC8J candidate. It does not promote that build. The public demo listed on itch.io is 0.93 RC; the older Visual Book retains its own version label.
