Twin stick shooters are my absolute favorite. The aiming mechanic seemed very interesting and different, but didnt appear to do much to change the gameplay. I would be curious to see results from experimenting with that. Never could take down a UFO, they're just in and out so dang fast. The characters are also endearing, I wisj I had had the chance to see them from another angle where we could get a good look at our hero and his foes.
