TypeForge: Cracking the Code of Your Own Typing Mistakes

This is a submission for the June Solstice Game Jam TypeForge: Turing-Inspired Intelligent Typing Coach What I Built TypeForge is a premium typing coach aligned with Apple's Human Interface Guidelines, built to help typists build speed and accuracy through automated, localized error diagnostics. TypeForge analyzes keystroke performance to isolate specific character transitions that cause delay or accuracy drops, then generates custom, adaptive exercises targeting those weaknesses. Developed for the June Solstice Game Jam, the project celebrates the power of computing and accessibility by turning raw diagnostics into a personalized educational experience. The solstice theme represents the journey of transition: taking a typist from darkness, meaning slow, error-prone typing, into light, meaning fluid, expert flow.

Development was accelerated throughout using Google's agentic AI coding assistant, Antigravity. I focused on clean Apple HIG spacing, micro-interactions, responsive scaling, and high-fidelity audio feedback to create a tactile, premium user experience. I also engineered custom canvas-based timeline sparklines to avoid heavy graphing packages and preserve maximum load performance. # === SYSTEM ARCHITECTURE === # app/ # Next.js pages including Settings and Profile views # stores/ # Zustand stores (typing-store, stats-stor
