Techno Kitten Adventure is a game we missed reviewing upon release here at Appspy. Most likely since the reasoning behind which free titles we review is constantly evolving (and hey, if we don't review it, the game is free. You can see for yourself if it's any good).
For fans of this game and also those who love the internet meme of Nyan Cat, 21st Street Games is releasing a Nyan Cat pack in the next week for a $0.99 in-app purchase. It includes a whole new song, and three unlockable Nyan Cats. Here's the trailer, and i'm going to stop saying Nyan Cat now.
