Gameplay
The player controls a ship which can fire and move left or right. The player must continuously monitor the onscreen temperature and fuel gauges. If the ship's laser overheats, it is disabled until it cools; and if fuel is depleted, the game ends regardless of how many lives the player has left. The player must battle through waves of enemies, which attack with varied formations and flight patterns. When a wave is destroyed, a new one appears. The Warp function is usable once per sector or life, temporarily slowing all enemy vessels and making them easier to shoot. At the end of each sector, the player flies through an asteroid belt and can obtain extra fuel by shooting fireballs. Then the mother ship is met, where the player docks and refuels for the next sector. The player is rewarded for completing each of 25 undisclosed tasks or "secret bonuses", such as shooting all enemies in a specific order or shooting all enemies without missing.Reception
