That looks like a useful link, I'll add it to the game description so it doesn't get lost! That site DOES need a search function or some tags, but I imagine it's only just been made so it makes sense it would be a little basic.
Thanks for linking my game there though!
I did see a reddit post that itch was possibly going to re-index NSFW games that were being given out for free, but the post seems to have been taken down.
