heromit, I'm really sorry for the duplicate key and inconvenience, and thank you for allowing me to delete the giveaway. I contacted Bunch Keys for this matter and requested for fresh key, I will let you know when I got the answer, I'll try my best for you to get the game!

Hey, Bunch Keys just answered me that the key was indeed duplicate and batched a new freah key, I just replace it and put the new key so please try redeem it and let me know if it works!
