The Crystal City

The Crystal City is a 1-player flying horizontal shooter. The player controls a fast-moving jet that can maneuver in all directions, and fires directly forwards. The player fights alien planes, helicopters, rockets, turrets, and other dangers. The player has limited shields, and must pick up parachuting energy before it is hit by friendly or enemy fire. Striking the ground is an immediate game over. There are 6 levels in total, and each level has a boss fight at the end.
