The winner will receive a gift link via Humble Bundle. Please note that the key is not available for those in Germany (sorry - not my decision!) - according to Humble:
"Region Lock Warning
This key is not available in the countries listed below. If the person you're gifting this to lives in one of them, Steam might prevent the key from being redeemed.
DE"

So please don't enter if you live in Germany as I can't guarantee the key will work.

Good luck and have fun :)
