I'm sorry about that. I grabbed the game off of Tremor the other day, and when I tried to redeem the key, it said that I already owned the game. Looks like that message was just a glitch though, as steam says that I acquired the game yesterday (which is when I tried to redeem the key). That sort of thing happens on rare occasions. I should have double checked though before creating this giveaway. I'll make sure to do so in the future.

In the meantime, I just grabbed a second key off of Tremor. Check your games won page for the new key. If for some reason, there is a problem with that new key, let me know. It should be good though.

Again, I'm sorry about the mistake.
