offers two control methods. Motion control uses the iPhone's built-in tilt sensor, allowing you to aim the cannon by tilting the iPhone to the left and right. The other, Touch, places a level at the bottom of the screen, allowing you to tilt the cannon by moving the level left and right. Both offer the same level of control, though I found the Touch method a little more responsive. However, this is a personal preference. A thin white targeting line that shows where the ball will go also aids aiming. Additionally, angle guides appear on the sides of walls, making trick shots easier.
Causing balls to fall will sometimes unlock power-ups to help clear the board quicker. One, the Sure Shot, gives you a "laser pointer" that shows exactly where the ball will go, while Bomb Borb clears out surrounding balls. Others allow you to choose which ball will be the next out of the launcher or blast through the board, taking out any balls it touches. No doubt, power-ups are a great help and the balance feels right. You don't see them in every level, so when they do come up, it feels special.
Bubble Town is a great fit for the iPhone. Games are easy to understand and take only a few minutes to complete, making them ideal when you don't have a lot of playtime.
