I have a couple old Humble Bundle keys to give out.
To enter, make a relevant/meaningful post on any community, and comment here with a link to it. It can be anything from a song on a music community, game patchnotes to the game’s community, or even just a meme posted to 196 or something. So long as the post is on-topic and within the rules, its good enough. I’ll pick a random valid comment in three days, and send the winner the keys.
Actually, its a tactics/puzzle game, structured similarly to Xcom, but much smaller and and simpler. I enjoyed it a lot myself as a nice casual game.
Heres the store page.
