HOW THIS WAS BUILT

This whole game was built through conversation with Claude Opus 4.8 using Claude Code, inside the LevelCode editor — starting from a 2012 Super Mario HTML5 engine.

🎨 Every sprite is generated by code — a hand-written pure-Python PNG encoder. No image files, no art tools.
🔊 All sound is synthesized live in WebAudio. No audio assets.
🗺️ Levels are procedurally generated from tile arrays.
⚙️ 5 biomes, crafting, tameable pets, an Ender Dragon boss, day/night & block-building — each added by just asking.
