Now the most interesting part - the development. I used three.js and vanilla js, no engines or frameworks at all. The critical part was to get the story, organize self testing process - game is challenging, units are clear, gameplay brings joy, no UI mistakes, etc. Other important part was to use subagents which focus on different tasks, AI downloaded the blender and music generator and provided enough of cool features to the game.
I am really proud of what I can achieve in 2-3 days , I played it myself over 10 times and every time I was enjoying it. not AAA, but can compete with indies.
