FYI: There’s a reddit post talking about how to get your game for free. Letting you know as it really rubbed me the wrong way and imo they definitely will have to take it down if you say something. Either that or maybe you can reach out to Steam about the problem.
Edit: Apologies if this wasn’t the best place to share this issue - I just wanted to ensure you knew about it as soon as possible and this was the only way I knew to get in touch!
Edit again: Decided to remove the link to the reddit post, but let me know if you want that info.
