NEWS

With more than 40 articles published, we reorganised the site.

• Article list moved to the front page — the separate blog index is gone; articles now live on the home page and can be filtered by GUIDE / SCIENCE / NEWS / REVIEW / KIDS
• Share buttons on every article — post to X or copy the link from the end of each piece
• One project mark throughout — the Earth-and-Moon infinity symbol now appears on the home page, author box and social images
• FAQ reorganised — split into “About the blog” and “About the game”, with new entries added

• Tutorial rebuilt — aiming and the slingshot step were reworked so your first clear is guaranteed
• Planet card reveal — clearing a Solar System stage for the first time now shows that planet's card between stages, flipping to a real NASA photo

• Planet encyclopedia (9 pages) — key figures, characteristics and trivia for each planet, illustrated with NASA public-domain photographs
• Collection reveal — newly collected planets and constellations now lead you from the results screen to the encyclopedia to watch it fill in
• New launch animation — a point of light now traces an infinity loop between the Earth and the Moon in a single stroke

• Artwork overlay (all 30 constellations) — classical figures aligned to the stars, toggled with LINES / ARTWORK, with pan and zoom for the details
• Rank always shown on the results screen — players without a display name are now invited to set one after a clear
• Display-name filter — impersonation and inappropriate names are now rejected on the leaderboard

• English-only article pages — articles likely to find English readers now have their own /en/ pages
• Contact form — a simple form so it's easier to get in touch
• Account linking improved — unlinking no longer deletes your data, and deletion now propagates to every linked device

A continuous run from the Sun outward — how far past the Solar System can you get? Launch it from “✦ ENDLESS” on the title screen.

• Checkpoints, items and one-light-year warps give it a different rhythm from the campaign
• A separate leaderboard — compete on distance, with your personal best and the top records drawn on screen as targets

We've rolled out several improvements to the Gravity Weaver official website.

• New Contact Page — A dedicated page with email and social media contact information
• Footer Navigation Improved — Direct access to the contact page from all pages via footer links
• Collection Page Published — View your in-game scores and planet collection in a dedicated page
• SEO & Metadata Enhancements — Structured data, OGP, and sitemap improvements for better search engine visibility

We've published a detailed Game Guide page explaining in-game mechanics, plus individual Constellation Encyclopedia pages covering astronomical data, mythology, and observation tips for all 30 constellations.

• Gravity Well vs Slingshot strategy breakdown
• Complete item effects list and selection tips
• Detailed constellation data (magnitude, spectral type, how to find, mythology)
• In-game strategy hints for each constellation area

Gravity Weaver is now officially published on the indie game platform itch.io. Play directly in your browser.

• All 147 stages (9 solar system + 138 constellation) available
• Global leaderboard support
• Bilingual support (Japanese / English)

A major update focused on improving game quality and strengthening the development infrastructure.

• Code Quality — Major refactoring of GameScene and SoundManager (modular architecture for better maintainability)
• Testing — Introduced Vitest unit testing framework with 13 physics engine tests
• CI/CD — GitHub Actions pipeline for automated builds, type checking, and test execution
• Accessibility — Improved contrast ratios, skip links, ARIA labels, and semantic HTML
• Google Analytics 4 — Event tracking for in-game actions (stage clear, item selection, etc.)
• Security — OAuth CSRF protection, rate limiting, and removal of deprecated SDK code

The official release version (v1.0) of Gravity Weaver is now live, featuring the following major improvements:

• Enhanced Visuals — Score count-up animation on game over, NEW BEST effects, revamped title screen animations
• Sound Upgrade — Context-reactive BGM (tension drones / zone-based chord progressions), ambient pads
• Haptics — Vibration feedback synchronized with in-game actions (toggleable)
• Accessibility — Reduced Motion support, improved contrast, skip links, ARIA labels
• Performance — Physics buffer reuse, background rendering cache, and other optimizations
• Tutorial Improvements — Phase 2 timeout re-guidance, item selection conflict resolution

Development has begun on Gravity Weaver, a space puzzle game where you draw gravity fields to guide particles of light.

• Draw gravity fields with your finger or mouse to guide Solar Shards to goal planets
• Realistic gravity physics simulation
• Stages inspired by our solar system and real constellations
• Browser-native development with Phaser 3 + TypeScript
