I've already written about Doodle Jump, but new comer Spin Crazy has piqued my interest and I've only played for about 6 minutes. I get this feeling from apps that can be read as either "I'm going to play this one a lot," or "I'm done already."
Some of that may be a matter of personal opinion. In other words: I'm not into RPGs all that much so am I really going to enjoy an iPhone RPG? Or: I like puzzle games and a mobile platform is perfect for puzzle games.
Enter Spin Crazy. I'll be playing this one for a review at The iPhone App Review. I'll be sure to let you know when it goes live.
