I have a duplicate key for that game, so I am giving one away for free. I played this game already and I think it was good: https://store.steampowered.com/app/746850/Cloudpunk/
To get the key you have to submit your email here: https://www.humblebundle.com/gift?key=ZWyyc2Su7BNBpr7z You might have to register too, I don’t know.
First come - first serve.
Giving away keys is always a nice gesture. Keep in mind to not share the key in a post, though. There’s bots created for Reddit that will look for keys, I wouldn’t be surprised if something similar is available, or soon will, for Lemmy.
