A vertical STG where you wiggle the joystick back and forth to melee attack on your flanks. It is painful to play the way it was intended--slamming my arcade lever back and forth for a play session not only felt horrible, but also seemed potentially damaging--so it's nice that the ports of the game include the ability to map auto-wiggling to a button.

This, however, sort of breaks the game? The melee side attacks are not only incredibly powerful, but integral to scoring; and with the auto-wiggle, both scoring and surviving the first level becomes essentially automatic. Of course, the difficulty increases dramatically from there, but I couldn't help but feel weird and distracted throughout as I "cheated" many of the game's enemy patterns.

That's not the biggest deal in the world, really -- there's still plenty of difficult shmup gameplay here if you want it -- but, after a couple rounds, I concluded that this particular blend of melee, zero-damage bombs (they just provide a field of invincibility from bullets), and rather ineffectual vulcan shot just isn't for me.
