Weird. I can't pass UFO in Normal, so I put up someone else scorefile. (I feel ashamed! -_- ) The EX stage was unlocked, so I went straight away playing. Until I lost to the stage due to getting to know the Danmaku patterns well but in my fifth try I passed it! (With only losing about 2 lives in total!)
Well that proves we all have our danmaku differences. . . . ^_^
