Another game that I've had since launch is Spinner Prologue. This is another game that is played using only the accelerometer. Essentially this is simply a set of mazes that you must navigate your way through. However, rather than controlling the arrow, it moves in a single direction and you must rotate the maze in order to lead it to the end.

This game can be very frustrating at times, as it is not the easiest of titles. See, you don't just have to navigate to the end of the maze, but you also can't touch the walls. As the levels progress, you must navigate through tighter turns and more narrow areas. I've only made it to level 11 so far, but I'm determined to beat the game.

A couple things to note when playing this game. First, you need to start ever level by holding your phone vertically. Second, under no circumstances should you ever double-tap your screen. I'm not sure whether this is intended or a bug (I'm going to go with bug) but doing so will take you back to the very first level.

Spinner Prolouge takes up just 0.6MB of space, and is free. There are only a few levels, however, there will be a paid version of the game later which will have more to play.
