App Store Description

In the early 80's computers were unable to draw complex 3D graphics with realistic full-frame rendering. Games like Asteroids used vector graphics to create smooth movement. Walls is a remake of a game using this technique based on a 1980's game named Star Castle.

You fly a small spaceship, which can rotate, thrust forward, and fire small projectiles. To rotate the ship move your thumb up and down at the leftmost side of the screen. To thrust tap with two fingers at the right side. Fire by tapping the screen with one finger on the right; hold down your finger to fire at maximum rate.

In the center of the screen is a stationary gun surrounded by three concentric, rotating, ring-shaped energy shields. The shields are composed of nine sections each. The objective of every level is the same; to destroy the gun inside the shield rings.

To do this, blast through the shields. Shooting once at a shield section causes its color to fade, and a second hit destroys it, creating a hole in the shield ring. This exposes the inner rings to fire. Once the innermost ring has been breached, the gun is vulnerable. However, this also works against you, for not only can you fire in, but the gun can also fire out, with a strikingly more powerful armament.

The gun tracks your movement all the time. If you manage to hit the gun, it explodes violently, collapsing the shield rings. The next level then starts with a new gun and fully-restored shield rings, with the difficulty increased.

Apart from the gun's firepower, there are two other things that impede your progress. Firstly, if you destroy the entire outer shield ring, the shields regenerate - the middle ring expands to replace the lost outer ring, the inner ring replaces the middle, and a new ring replaces the inner. Therefore, you must fire decisively.

Secondly, the gun has another defensive mechanism. Magenta sparks inhabit the ring and can detach and home in on your ship, destroying it on contact. The sparks can be destroyed, but they are very small and difficult to shoot. Destroyed sparks can regenerate from the shield rings.

As you progress through the levels, these sparks get faster and faster, forcing you to keep moving to avoid them.
