I Pitted Gemini CLI Against Claude Code to Create Flappy Bird

I was curious to compare the new Gemini CLI with the new incumbent Claude Code, so I prompted both to create a Flappy Bird game from scratch.

Claude Code - took just one prompt - nice UI styling - high cost, ~$4, with opus 4

Gemini CLI - FREE - lots of fixes needed after first build - auto switched from 2.5 pro to 2.5 flash midway due to "slow response"

You can find all the code generated on GitHub: https://github.com/kstonekuan/gemini-v-claude-flappy-bird

I'd love to hear your thoughts and feedback!
