About this game
Spellblunder is a free browser-based 3D wizard game where you combine elements into spells that frequently backfire. It offers a five-chapter campaign, an arena, online co-op and duels, and bot opponents. The game supports six languages and is playable on desktop with keyboard and mouse. Claude Code (Opus 5.5) wrote the code, while the developer handled the ideas and playtesting; the author talks to Claude in French and used ElevenLabs to generate and compare sound variants on a listening bench.
