Developer Ships HTML5 Game Using Claude Chat Free Version

Project Overview
A developer with previous experience writing games in C using the Allegro game engine two decades ago returned to game development using Claude Chat's free version. Over approximately 30 days, working about one hour per day, they built a complete HTML5/CSS/JavaScript space shooter game called Swarm Sector.
Game Features Built with Claude Chat
- Single HTML5/CSS/JS page implementation
- Procedural sounds for weapon effects and other game actions
- Enemy AI systems
- Upgrade mechanics
- Escalating wave progression
- Performance comparable to small Unity projects
Claude Chat's Strengths
The free version of Claude Chat proved effective as a coding assistant despite occasional usage limits. Key capabilities included:
- Fast, tireless coding assistance
- Solving tricky functionality that would have been challenging manually
- Rewriting messy logic loops
- Auditing and solving performance-related issues
Claude Chat's Limitations
The developer noted specific areas where Claude Chat fell short:
- Game design intuition - it cannot determine what's fun
- Balancing combat or upgrade systems
- Understanding subtle performance issues like cursor animation loops consuming frame budget
The developer concluded that while Claude Chat Free can help build a modern-feeling browser game, the gameplay, fun, and soul of the project still come from the human developer. The completed game is available at https://pajujo.itch.io/swarm-sector.
