Alex O'Callaghan created a Minecraft-themed phonics game during a conversation with the AI model Claude. The game has two modes: one for picture-to-spell using letter tiles and another for read-to-picture with four images, targeting Key Stage 1 phonics. He developed the project further using Claude Code, set up Vite for development, integrated Vitest for testing, and switched to TypeScript. O'Callaghan enhanced the game's visuals by using a comprehensive npm package for Minecraft item sprites. His son engaged with the game and contributed content suggestions, improving their connection and motivation to practice phonics.
