Developer duo Serenity Forge and Moonana have unveiled a significant update for their game “Heart Strings” on Steam, which includes the addition of new characters to romance, new items for backers, support for additional languages, and numerous other enhancements.
Last month, Moonana gave us a sneak peek of what’s to come with the upcoming update, especially when their game was offered at a discounted price during Steam Daily Deal. Excitingly, Black Holes from Moonana’s “Virgo Vs The Zodiac” are making a comeback in Keylocker, now featuring roguelite mechanics!
The update also brings some fresh additions such as new party member hats, an improved Quest Menu that allows you to track the location of your selected quest on the map, and much more, which you can learn about in detail by checking out the extensive patch notes below. As a fan, I can hardly wait!
Keylocker is now available for PlayStation 5, Xbox Series X|S, Nintendo Switch, and PC (Steam).
Below, you’ll find the complete details about the Keylocker Heart Strings Update, including the patch notes and an update video, courtesy of Moonana. Enjoy!
