Hi there, this copy is unfortunately a humble bundle link and just a leftover from the bundle.
I bought this game using no amount of real money, if you guys remember the post about launch.stellar.org
They gave me 3 USD of bitcoins which I used to buy the bundle.
If your gonna register there, there's a part where you send money to someone but there gonna give you 1000 stellar "coins" for doing it. I'm just asking to send that money into my account "larongbingo".
That's all and Good Luck. :D

PS: My copy of QUBE didn't have anything written as Director's Cut, so in compensation I'm gonna send you an additional game.
