I won the sweepstakes for a copy of Superhot and Superhot mind control delete but I already have them in Steam.
Here is the key to redeem them on GOG.com if anyone is interested.

Someone has already redeemed it.

Thanks for giving it out (I did not redeem it though).

Next time, if you have a GOG key you don't want/need, please consider donating it to the community giveaway here: https://www.gog.com/forum/general/the_community_giveaway_gog_edition_redux/page1
