Following up on the card game I built with Claude after trying Codex

A while back I posted here about building Cash Stash with Claude. Claude helped me work through the React/TypeScript game logic, the hidden-information search behind the Hard AI, and Firebase multiplayer. It was genuinely useful for getting a playable game together. I cancelled my Claude subscription before September, so I can't speak to its recent versions. After that, I used Codex to keep working on the same codebase. The difference I noticed in my own sessions was workflow. When work crossed the code, PostHog, Cloudflare Pages, and Firebase Realtime Database, I found it easier to keep moving with Codex. It also found relevant documentation and my earlier Reddit feedback more easily, kept the surrounding context, and tried another route when it hit a blocker. In my earlier Claude sessions I more often had to step in when it stalled. I didn't run identical tasks through both tools, so this isn't a benchmark. The October commits show what I actually shipped: more reliable online synchronization and retries, a phone-first reskin, a better guided tutorial, clearer challenge timing and card faces, and post-game feedback with online takeover diagnostics. Player feedback about confusing steals made me realize how much work remained after the game logic was functional. If you've used both tools on the same project, what specific task showed you a meaningful difference? I'm especially curious about long-running projects where the assistant has to understand existing code and user feedback. The game is free to try, with no signup: https://caprocket.itch.io/cashstash   submitted by   /u/amae39   to   r/ClaudeAI [link]   [comments]
