Invasion from the 2nd Dimension is an old school arcade style game.

The player controls a space ship by tilting the device and bounces an asteroid into oncoming enemy Sprites. There are several types of sprites. New sprites types begin spawning as the players score goes up. Each time the asteroid hits an enemy the score goes up and so does the score multiplier. When the asteroid hits the ship the multiplier reduces by 1. If the Asteroid hits the Earth, the multiplier resets to zero.

The Earth takes damage as the sprites get to it or the player drops the asteroid. It is the visible indication of how you are doing. When it is fully destroyed, you lose and your final score is displayed.

In addition to the Invading Sprites there will occasionally appear power-ups such as a shield, anti-gravity for the ball, or the Power Ball, which passes through sprites without bouncing off.
