Completed 4 different runs of this game, and while I enjoyed most of them I have to say that the Zangetsu solo run on Veteran was not very fun in the later levels. It is really rewarding to get faster and faster at these levels, although I do wish there was a difficulty between 'watch your limited number of lifes disappear as you get knocked into the void constantly' and 'baby's first videogame,' but otherwise it is pretty good for what it is.
