Hard. Thats all it has going for it. Its so hard, that grown men have been brought to tears!
This game is truly horrible, in every sense. The fact it has colour is a miracle. The sound is bleeps, and its a clone of R-Type styled games. The difference is they at least give you a chance. This just unleashes hell on you. Literally. The only reason people play this game is because its the most difficult game ever devised!
However, depending on how good a gamer you are, it does get easier as you play through. But it still loves to snatch victory at the last second, then pummel you into the ground.
I'm sounding poetic, so I'll keep it brief. Play it, but only if you want to be driven so mad, that the people you know and love dearly, will from that moment on, know a different man!
