Hello! Thanks for playing so far and reaching out!
Indexing: I double-checked this to make sure, and the game is showing up for both me and a friend in search and browse. It's possible that your account has the adult content filter enabled, which is on by default (game got flagged on 2.0 launch) but as long as you're logged in and have this filter off you'll see it, as far as I'm aware.
Errors: While going back through the game to make Retrospective 2 (edit: available now), I have already cataloged all the grammatical errors I saw. I haven't had the bandwidth to work on a proper patch yet, but I hope I can provide one in the near future. (edit: patched)
Thank you for the enthusiastic support, I'm so happy you can share the game with others. Also I look at your Celia fanart daily, its so damn good
