Update: Instead of removing the product, with assistance of SteamWorks support, I've updated the pricing to free. Keep in mind, this product isn't supported so it could stop working at any time, however, it's free to add to your library.
Original announcement:
Hi everyone, Stream Buddy will be discontinued as it is no longer being updated. Regrettably, SteamWorks lacks a feature for developers to deactivate sales, hence I am currently seeking Steam Support's assistance in deactivating the sales page.
Thank you to everyone who gave Stream Buddy a try. While there's a possibility of updating it in the future, my current schedule doesn't allow for it.
Wish you all the very best.
