Hello there, and thanks for downloading Quillax's NetKeen Levels! To play them, you can just extract them to where the vanilla NetKeen files are at (should be in the 'game' folder), overwriting them. After that, start up NetKeen (one way to do this is to use DosBox), and if you're playing with Vorticons, Dreams, 4, or 6, you should then be able to find my levels after the original ones. If you managed to do so, then I hope you'll have fun playing them with others!
