rukito does have interesting gimmicks. im not too much of a fan of grs needle tower, where the second room has spots in the floor where it can kill you.
i do take back gr. the worst ive played is seven trials, but only because of the fact that ther are no gimmicks other than intricate jumps (if that can be called a gimmick)
edit
onc again, take back.
i wanna be a brute of a man. backgrounds give me headachesa and music is unoriginal.
