"At the time of release in 1988 there wasn't a helluva lot of 4th generation shmups around bar a handful of early PC-Engine titles, so graphically this looks better than most of its peers. The bosses look very imposing and the power-ups are more impressive than was commonly seen that year, with hectic, screen-filling weapons. I like the inclusion of being able to change between a tank and a jet on the fly, I think its a quite interesting gameplay mechanic but the implementation here leaves a lot to be desired. Musically the soundtrack is fantastic, but I find the fact that the sound effects cut out the lead of the music a bit distracting. The game is also a little bit short for 1988 in my opinion and the diffulculty curve is off."
