Source of light

User Summary: Source of light is a public domain shoot'em up written by Christoph Cemper in 1988. The games graphics reminds of the game Uridium, and is also a vertical scrolling shoot'em up in space, where the player can fly a spaceship left or right, and shoot waves of alien ships. The goal is to shoot down the aliens through the 8 levels. Hotshots (highscores) could be saved on disk or tape, and later loaded into the game again. There is also possible to load new galaxies (levels).
