Obsessed Lucy Steam 1.0 — Update 4 Launch

On 6 August 2026, VNGTrash published Obsessed Lucy 1.0 on Steam (app 3995190) with the news headline “Obsessed Lucy 1.0 is now available on Steam!” That storefront milestone equals Update 4 in itch devlog numbering: official launch notes cite +143 images, +53 animations, and roughly +4500 words beyond the prior stack that already included Update 1 (August 2025), Update 2 (+108 images, +26 animations, +4000 words), and Update 3 (+119 images, +13 animations, +3300 words). Windows, macOS, and Linux builds ship together; Family Sharing and Steam Cloud appear on the live feature list alongside Save Anytime, Adjustable Text Size, Custom Volume, Mouse Only, and Touch Only support.

VNGTrash also stated that development ended with 1.0, while bugfix updates may continue. Treat 1.0 as the creative finish line— not a early-access cliffhanger— when you plan replays or write reviews on Review and Worth Buying?.

What Update 4 / 1.0 changed for players

Launch-scale numbers matter because Obsessed Lucy is a short, mostly linear adult 18+ visual novel where choices flavor scenes and endings rather than opening dozens of unrelated routes:

• +143 images expand gallery coverage and environmental detail— completionists should rerun 100% Completion after upgrading from pre-1.0 itch saves.
• +53 animations add motion to intimate and confrontation beats; verify hardware on System Requirements if you play on older integrated graphics.
• +4500 words deepen dialogue, epilogue text, and optional reactions— cross-link Choice Points when guides mention new lines tied to friend-path or compliance clusters.

Mechanically, the game remains single-player with Steam Achievements (nine entries) as the primary meta layer on Steam. itch builds do not grant those trophies; see Steam vs itch.io before rebuying.

Steam feature checklist

The live Steam listing highlights features that shape daily play:

Feature	Practical impact
Save Anytime	Manual slots before finale clusters— see Controls & Saves
Steam Cloud	Sync saves across PCs; back up before OS reinstalls
Adjustable Text Size	Accessibility for long evening scenes
Custom Volume	Separate BGM, voice, and SFX balancing
Mouse Only / Touch Only	Input expectations for Ren’Py-style VN habits
Family Sharing	Library lending; achievements stay per account

None of these replace story knowledge on the Walkthrough Hub or Guides Hub— they reduce friction while hunting endings.

Nine Steam achievements at launch

Steam exposes nine achievements for app 3995190. Verified names include Tea, Birthday, Fake Boyfriend, Susan, and End, plus hidden entries No Decisions, End of Obsession, Husband, and Together in the Darkness. Full routing lives on Achievements and the achievement-to-ending map on Achievement Endings— this update page only anchors that they ship with 1.0, not behind a later DLC gate.

Use the Achievement Tracker while replaying; pair it with the Ending Checklist when a trophy and finale should fire together.

Relationship to itch history

Long-time itch supporters experienced Updates 1–3 as numbered devlog posts documented on Devlog & Patch Notes— including verified Update 1 footage (Ee2c_0aD8Kc) embedded mid-article. Steam 1.0 consolidates that pipeline for players who never followed itch, but save files do not automatically transfer between unrelated clients. Expect to replay on Steam for achievements even if story memory is fresh.

For Update 3-specific counts before launch, read Update 3. For storefront comparison, stay on Steam vs itch.io.

Post-1.0 expectations

Because creative development ended at 1.0, future patches should be bugfixes or store compliance—not secret route overhauls. If a hotfix renames an achievement string or tweaks a gate line, Ending Conditions and Achievement Endings update once English text stabilizes.

New players can start blind with How to Play and optionally Controls & Saves for Steam-specific habits. Returning hunters should prioritize Unlock All Endings and Friend Route before declaring the library complete.

Suggested reading order on launch week

1. Skim this page for scale and feature context.
2. Read Devlog & Patch Notes if you want the full itch timeline.
3. Route with Full Story Walkthrough or Routes depending on spoiler appetite.
4. Hunt trophies via Achievements after your first ending.
5. Confirm tone and value on Review and the Wiki overview.

Steam 1.0 is the reference build for this wiki unless a future bugfix note explicitly changes scene order— check the Updates Hub when new posts appear.
