It doesn't matter. They gave their word that the price would not go up. Why tell people that it wouldn't go up and then raise it so significantly? Also, I'm not sure if you are able to afford buying a game twice but I can't, I was planning on buying it on Steam when it released there but now since the price has almost tripled, I won't be able to.
I am disappointed to the level of not buying the game at all, and not just because I won't be able to afford it.
I'll just keep playing the version I have, the old free one.
