A blog post about the changes is cool, but I'd recommend an in-game guide as well. For final release, I'd shoot for an in-game Tutorial or even a guided run (tutorial first run basically), although I know that's way more work for you lol.
I also humbly ask as a fellow indie game dev, for you to check out my own game :3

I'm also trying to leverage AI tooling to establish myself as an eroge game dev. We should share notes! :)
