This is not mine-it is my brother's!
The instructions are already on the file, but I will put them here anyway. The planets orbit perfectly but you can fly a UFO around and knock them around for fun, like into the sun or something. The controls for that ship is ASWD. Also there is a huge mother ship floating around. Control it with 8456. The UFO can enter it if you open it with enter/shift. I created 2 other systems but erased them because their suns interfered with Sol's system. Anyway, have phun.
