It was actually a few months ago that the mysterious Steam algorithm finally decided that Lily’s Handmaid is eligible for trading cards. At the time I was busy developing Succubus Research Diary, though, so I didn’t release them right away. But now that I’ve had some time on my hands, I’ve put that time into making the cards and associated items.
The trading cards are complete and uploaded to Steam now, but they can’t be released before Valve has reviewed them. It shouldn’t take longer than 2-3 business days unless there’s something that has to be changed.
Edit: Turns out that there are a couple of things that have to be changed. This means that it will take a bit longer before I can release the trading cards.
P.S. I will make trading cards for Succubus Research Diary as well as soon as the notorious “Steam is learning about this game” status stops haunting the game. But it’s difficult to say how long that will take.
