I can give you for free 'Humble Weekly Bundle: Play and Create with GameMaker! 0$ free tier gift link'. It has only L'Abbaye des Morts + Source + Soundtrack and Spelunky Classic + Source) but you still can claim that page with that gift link to your Humble Bundle account and boost (increase) the amount recorded on that order from 0$ to for example 12$. You have time only to this Friday (October 23th) of Saturday (October 24th) maybe (30 days after the end of this bundle which had end 24th September 2015 probably if I'm not mistaken).
I just got more free gift links when they was available.
