prasenx · x · 2026-09-24
Developer prasenx shipped shinobi-duel, a Sekiro-inspired browser sword duel built by Claude Opus, now open-sourced on GitHub:
- Gameplay: deflect-based combat — win by breaking the boss's posture, not draining a health bar; a kunoichi vs. a samurai general on a snowy castle rooftop
- Assets: Mixamo characters, Poly Haven textures, a Blender-built arena; combat, boss AI, lighting and all audio are code (Three.js + synthesized sound)
- Requirements: 22MB download, wants a desktop GPU (tested on RTX 4060), playable in desktop Chrome/Edge
A showcase of what current coding models can produce end-to-end.
