What's particularly displeasing about this game's use of Kreds to buy in-game items, is that you cannot see what the items are or what their benefits may be until you have enough Diamonds for them to be revealed in the game, of which there are not enough obtainable through normal means to reveal all of them. Integrating the Kred system into games gets a bad enough response as it is, and asking people to blindly buy content for your game certainly cannot be helping matters.
