I have just rediscovered this game (I had always written this game off as crap; what was I thinking)
It is amazing, my current favorite. It is just as intense as Robotron but with amazing adrenaline rushing music.
I think what makes it work so well for me is the thumping music mated to the intense gameplay.
Wow; if you have the correct controls, give this game a try, super intense. When my last game ended, I was sweating and my hand was cramped from unconsciously squeezing the joystick too hard.
BTW, I'm looking for a link for gameplay hints/tips as well as game history. The included history.dat is pretty thin on details. Any leads?
