In which I play "Megalegs", published in 1982 by Megasoft. It was programmed by Mike Dubno. This is unabashedly "Centipede". It is quite well done. Game play is frenetic with a nice "arcade feel" to it. Sound effects are solid and they really give you a sense of what is going on in the game.
This gets a hearty recommendation from me, and you should play it. YOU should go play it RIGHT NOW! Don't wait. Do it now.
