Do yourself a favor and check out my disgruntled cousin Zigfriedhopov's Mami Inoue review, even if you're not the slightest bit interested in the title (and I don't suppose that anyone is), as the piece is quite good and very funny. I don't really have anything to add to what my thorough kinsman says about the game except that I find it to be so bad and so dumb that it actually ends up being pretty damn funny; and the "point and laugh" moments just keep on coming, as it moves along a lot more quickly than many of the other bad comic-style games for the Duo.
As perceptive Zigfriedhopov observed, there is an ever-so-slight difference between how Mami is presented and how all the other characters are.
Crudely sketched or not, the shades-wearing "coach" and the time-machine-eating dinosaur are impact characters who will never be forgotten.
The plot is quite the exciting up-and-down ride. Scenes of brutal violence are followed by uproarious antics.
