Thanks!

hey, tried to redeem but it says it is already activated.

I'm sorry, i had some old keys still marked as unclaimed in mi humble account and since i already have those games i was giving them away.
While almost every key was correctly redeemed by winners, there were some cases where the key turns out to be already used. I guess Humble Bundle has mistakenly marked them as unclaimed while there were actually already claimed by me.

If it's ok for you, i'll ask to delete the giveaway
