The listing, Ravensword: Shadowlands Steam link has ended.
First listing, sorry if I mess anything up :) I am too new to add GIN.
Steam lists this as Action Adventure Indie RPG
I have this item from an old Humble Bundle. Goes for $6.99 on Steam, but I'm sure I paid less for the whole bundle. Steam key only - Mac Windows Linux compatible. See second image: I will press the button to get the giftable link, then send that link to winner.
