This is actually two games - one a road-racing shoot-'em-up, the other a Rolling Thunder-style scroller. Neither game is particularly stunning in its own right, but coupled together they just about add up to an enjoyable package.
Purple Saturn Day is an excellent package... Not only is each game beautifully presented, they are all very playable, and there is such a variety that once you're hooked you'll be playing for weeks to come.
Phantom Fighter isn't original, but it tries to be a nice shoot-'em-up - the graphics are nice, the sound is tolerable and it plays reasonably well - but I'm afraid it just hasn't got anything really special going for it.
This is one of those games that really grows on you. I started off distinctly cool, if not bored and frustrated by it. However, by now, I am so taken with it that I am determined to see it through to the end.
