One huge flaw.
Something I notice when people try to make hybirds such as this is that they'll take on two separate genres of game, and think that they can pass it off as a good game if it's two half-baked games in one. Unfortunately, this logic doesn't work. The soundboard and dressup are both tired concept, and this one doesn't even scratch the surface of immersion that is required to even make a decent one of either. Wardrobe selection is very limitted, and not even relevant to the series. I would like to have seen some artwork that is from the show, and actually carries the same quality of art as Bender himself.
So I'll put it frankly like this. You can't take a half-done game, another half of a game, and put them together to make a whole. It just becomes two unfinished games sitting next to one another.
