INVESTIGATION / NARRATIVE PUZZLEBROWSER

Selk

Read between the records. Decide what the evidence means.

Browser play / demoSource availableFree external browser game; fictional name used for gameplay, not account creation

Creator’s ClaudeGameDev release describes AI-assisted development; creator-reported, not an independently measured authorship claim.

Reuse: GPL code, CC BY-SA story, CC0 original illustrations and OFL fonts retain separate obligations. No proprietary reference imagery included.

Play check: Hands-on inspected 29 Oct 2026: Reports 1, 2 and 3A accepted; full story not assessed

Reuse: Source linked; check code and asset terms before remixing.

Full play status & limits

Play: Browser at creator’s site

Remix: Pinned source; local build unverified; manual project setup and return review.

Runtime: Browser — desktop inspected; mobile not tested; network/server needs unverified.

Quality: No catalogue quality acceptance recorded

Revival: Revival suitability unassessed; no abandonment claim

Hands-on inspected 29 October 2026 on the official external game using fictional name Mira: explored site, lab, gate, structure and archive records; Reports 1 and 2 accepted; Archive unlocked using an in-game hint; Report 3A accepted by Audit Desk 4. Dense but readable multi-pane text interface. Report 3B, full story/all endings, audio, mobile and save/reload were not tested. Owned game tab closed after inspection. Bounded interaction evidence, not full quality acceptance or verification that the source pin reproduces the live game.

Remix with your AI →

A first idea: First reproduce the pinned original unchanged. Then make one small investigation case with a new evidence chain and report. Keep GPL program source and CC BY-SA story obligations explicit, preserve credits, test report unlocks and provide corresponding modified source. This is a suggested direction, not an existing case-pack importer.

Give this brief to your own assistant. It includes the pinned source, original credit, setup, reuse terms and a first task.

Source, setup & reuse terms

Investigate conflicting records on Titan, connect evidence and submit reports through a fictional research terminal. Hands-on inspection reached accepted Reports 1, 2 and 3A and unlocked the Archive. The creator describes six endings; no full story or all-ending completion is claimed.

Code & assets

Code: GPL-3.0-only program source. Preserve notices and provide corresponding modified source under the applicable GPL terms when distributing.
Assets: Story and documentation: CC BY-SA 4.0. Original Selk illustrations: CC0 1.0 to the author’s rights; RADIOSOL reference images excluded/not covered. IBM Plex Mono and VT323 fonts: SIL OFL 1.1 with per-font notices. Synthesized audio follows program-source terms; not a separate CC0 sample pack.

Original licence notices ↗ · Asset notices ↗

What you need

Pinned official source repository reviewed. Source/live deployment correspondence and a clean local source build have not been verified; the tested external original remains hosted by its creator.

  1. Open the official browser game. The terminal sign-in is fictional avatar naming, not a real account; use an invented name rather than personal information.
  2. Source is a static website with no package-install/build step according to its pinned README. Follow upstream instructions; an unchanged local source build has not been independently accepted.
  3. For redistribution or adaptation, retain GPL source obligations, CC BY-SA story attribution/share-alike, CC0 illustration provenance and OFL font notices separately. Exclude unlicensed reference images.

Bounded interaction evidence, not full quality acceptance or verification that the source pin reproduces the live game.

  • Creator describes a perpetual beta; six endings are an upstream feature claim, not six independently tested outcomes.
  • The original has an authorial political-economic viewpoint; it is fiction, not neutral science instruction.
  • RADIOSOL visual references are not included or covered. Do not acquire or redistribute those reference images as part of a remix. Visual similarity has not been independently assessed.
  • Free browser play and source availability do not imply every licence can be combined with any other game. No automatic compatibility, complete source build, security clearance or full quality acceptance claimed.

YOUR PROJECT COULD BE SOMEONE’S BEGINNING

Made a game?
Give it a future.

Finished or unfinished, browser or desktop: suggest your public repository and playable build. Include code and asset licences, what works, and one thing you wanted to build next.

About these listings

Listing, price and licence information is upstream-reported, not our gameplay testing or remix permission. Recommended prioritizes reviewed picks, then source-reported released games with free access, imagery and strong player-rating evidence. These are discovery signals, not our gameplay quality score. Most rated uses sourced rating/review counts, not players. Device and engine filters reflect source reports; Godot is an engine, not a platform or quality certification. Unknown counts rank last. Price reports do not establish original-content rights or working gameplay. Curated source foundations are additional project guides; main search includes their matching entries. The listing count does not silently add or double-count those guides.
