Game is no longer available on Steam. Key is from OtakuMakers' Go Go bundle Mega #12. Possibly risky giveaway, given the number of revokes lately. This bundle is from back in March 2018 and all keys except one other have been used. So if the key does not work then I will hope you will agree to delete the giveaway.
There are some keys that I have from a different bundle that I want to offer free. The bundle is Bunch Keys #19 and the games are Headache (removed from Steam), Paint Skills (removed), Scarecrow (removed) and The Bridge (removed, has same name as the decent game still on Steam). This last game, the Bridge was supposed to be launched on Steam on 23/3/18 but I cannot find it's game hub so suspect it may have been banned before it was launched. If this is the case the key will not work.
If interested in any of the free games, please leave me a message. I will friend you and message you the key.
