IMPORTANT NOTE: do not enter this giveaway if you already own the base game. This key will not activate anything.

I got this as part of the current TinyBuild B.Y.O.B. on the Humble store. I have the base game and tried activating this key thinking it would add the bonus content, but it just tells me that I already own the game.

If you don't own the base game and you win, and the key still doesn't work, then you agree to delete the giveaway, but I have no reason to think it won't work :)

Good luck!
