You guys are morons. You don't "need" kreds to play the game. Sheesh. It's just extra features that probably make the game way too easy if you have them.
"herp derp i dun like dis game cuz you haff to bai stuff durr hurr"
Not many people would spend legal tender on a tower defense game, but those are just extras, and i think they would make the game way too easy. Stop complaining that you can't get extras and this game is so unfair blah blah blah.
