Give me a little time, it was part of an Indie Gala bundle and there have been issues with keys for this game.
I am gonna try and get a replacement key, but since it is the weekend, it might take a few day.

Thank you very much for the offer of deleting the giveaway if I can't replace the key, it's appreciated!

Just sent you a new key through steam chat, let me know if this one worked!
Was surprised that IG responded during the weekend.
