In pre-astronautics, there were supposedly many peoples who had already flown into space, including the Greeks, Mayans, Egyptians or Chinese. You travel with your spaceship and encounter some of these peoples again in space.
Collect the light blue crystals with your spaceship to fuel it up. You can use your energy cannon to shoot down objects in your path. Be careful, the energy cannon also needs fuel.
After you have collected 20 crystals, a new boss awaits you, which you must defeat to progress. Here, you have unlimited energy.
Points:
Collecting crystals gives you 10 point and refills your fuel.
Each destroyed enemy spaceship earns you 15 points.
At the end of each level, you receive a 10-point bonus for every shield unit.
Before each final boss, you gain an additional shield unit.
Controls - Arrow keys (up, down, left, right) and Z and X for the buttons. Q starts most games, but unsure of the difficulty. The numbers don't work in this online emulator.
