I really wanted to like Ant Blox. It's a great concept for a puzzle game: stack some blocks so that an ant can easily walk to the other side of the level to reach an apple. Unfortunately, Aleph Games doesn't seem to understand smooth game mechanics. The first couple of levels passed without incident, but as you increase in levels, you suddenly realize that this is a game that's easy to learn, and easy to screw up.
I love games that use the accelerometer, and the concept behind Ant Blox's use of this device is wonderful. Tilt your iPhone around to allow "gravity" to move the blocks into whatever position is appropriate. That's cool. A bit of a Tetris idea with a more organic twist. The problem comes when you understand that these blocks don't really have any weight to them.
