I've been playing a lot of island life simulation games lately, and found myself constantly needing better tools for: 1. Creating pixel-perfect custom avatars 2. Managing QR codes for multiple villagers 3. Figuring out compatibility between residents So I built LifeSimGrid — a free, open-source, 100% client-side web toolkit designed specifically for these games. 🎨 Pixel Studio 1. Multi-ratio grid support (256×256 square, rectangular covers, widescreen wallpapers) 2. 4 grid density options from 1px to 7px precision 3. Built-in brightness/contrast filters to reduce color distortion when downscaling 4. Paint-by-numbers highlight mode for easy tracing 🔓 QR Configurator 1. Batch drag-and-drop QR code images 2. One-click unlock "anti-copy" and "non-editable" restriction flags 3. Online safe rename with automatic checksum recalculation 4. Client-side ZIP packaging for batch export 🔮 Voice & Relationship Lab 1. 8-bit voice simulation using Web Audio API (sawtooth wave + lowpass filter) 2. Zodiac & personality-based compatibility calculator 3. Local resident roster with relationship leaderboard All processing happens locally in your browser — zero data uploads, zero tracking. Built with Next.js, TypeScript, and Web APIs. 🔗 https://lifesimgrid.org 📦 https://github.com/cenyi/LifeSim... Would love to hear what you think — especially if you're into life sim games!
