Not as good as the the rest
The biggest problem with this game is the array of bullet fire your expected to dodge is impossible try the the PAL-1000 the turrets spread to much bullet fire and can go through certain platforms which makes it even more difficult its like you have to die over and over just to advance against bosses (kill one turret die go back kill another die ect)
And there are extreme quantites of enemies in certain areas kind of reminding me of contra
i really think you should dim down the amount of bullets in certain areas
it might also be easier to go in a set pattern but there is no specific pattern maybe it would have been better if you numbered the teleport areas
decent game but i really think the first game was better the others are really that impressive
