Clearing out some old keys - for games that I already own or don't want.
Source: Humble Weekly Sale: Frozenbyte - Jan 2014

As there is always a chance that a key might not work (especially for old bundles), I kindly ask for your permission to remove this giveaway if that happens. It would be much appreciated.

Please, there is no need for comments giving thanks - I would prefer to avoid the messages spam.
