I think that the other question is "what do we mean that Gemini 2.5 built it" - was it with a prompt like "build me a missile command game with a reward system that will enable me to buy upgrades"? Or was it interactively with the dev?
1. Used https://gemini.google.com Gemini 2.5 Pro canvas mode for Gemini Advanced subscription account to ask it to build Atari missile command game in HTML5. Tweeted about it at https://x.com/George_SLiu/status/1906236287931318747 almost one shotted but after I passed level 1, it jumped to level 182 and pulverised my cities and bases LOL
2. Iterations in subsequent chat sessions in Gemini web to fix it up, add in-game store, leaderboard and end-hame AI analysis and when Gemini 'something went wrong' messages, jumped over to Claude 3.7 Sonnet via Claude Pro subscription web interface to finish off the task
3. A few days ago, I tried Cline with VSC for the first time with Openrouter AI API key and Gemini 2.5 Pro free LLM model has helped me with further development. Also now trying out Google Firebase for more Gemini 2.5 Pro access https://studio.firebase.google.com/ ^_^
