Nice job. FYI there have been a couple of attempts at an RTS LLM Arena with varying degrees of success.

And of course there's a ton of research into more traditional forms of AI playing RTS games such as Alphastar.

Feedback:

That percussive sound that starts the song at the beginning of Play is SUPER jarringly loud. I'd trim it out of the track entirely.

I know you've mentioned tileset improvements but just to put it out there you've generated isometric buildings, but the tile set you're using appears to be square based. This creates a very incongruous style where the buildings don't feel like they're actually attached to the ground.

Finally, about the pixel art you’re using: you’re asking Nano Banana to generate it, but there are a couple of issues with prompting pixel art from GenAI models. The most obvious one is that the pixels aren’t aligned to a traditional grid which leads to really noticeable fringing. This is especially obvious when I use the scroll wheel to zoom in on some of the art assets.

I’d highly recommend using something like Unfake [1] to clean this up, aligning pixels and reducing the palette to something more consistent. It’s a bit more manual work, but it will make your assets look dramatically better.

Here's an example of where I demonstrate generating better sprite sheets with NB:
