[PC] FREE Steam Key - Melissa K and The Heart of Gold - Indiegala (FB+Twitter Required)(71% positive; trading cards)

Another freebie from Indiegala but this is different to the usual ones.It looks like a competition but you just do it more than once if you do not win first try. You will eventually get a key (my friends did and this is how it worked on other "competitions" like this before).
Follow the instructions /actions as set out on the page to get your key. Facebook and Twitter required.
As far as I can tell the compulsory actions are: following on Twitter/subscribing to Youtube channel/signing up with e-mail.

Enjoy.
