Ms. 'Splosion Man has plenty of game, but her charm is almost non-existent. Everything I loved about 'Splosion Man—the gameplay, style, music, and charm—found its way into Ms. 'Splosion Man except for the charm. This lack of charm is due to an abundance of dialogue from the title character and her "nails on a blackboard" voice. Quoting 90's female pop songs is a great idea, but saying them over and over again every thirty seconds is a horrible idea, especially when there isn't much variety. There was a point when she threw out three separate quotes in about fifteen seconds and I just wanted to slap her.
I relieved this annoyance by muting the vocal-specific audio, but this only managed to remove an irritation and did nothing to add charm. Getting past my distaste for the choices made specifically with the character, the game is still fun for the most part. The gameplay is basically identical with new aspects added on a fairly regular basis and some really well thought out level design; however, the camera can force multiple attempts due to cheapness and not user error. The visuals are improved and my favorite part of the game is without question, the music. I eventually stopped playing because a charmless game is not as enjoyable as a "charmless man" and I ceased having any fun.
I am likely in the minority with my feelings towards her voice, but taking the trial for a test drive will help you decide for yourself. And now I wish to say one last thing: I made it to around level 2-9 or so and Mandy is still, by far, my absolute favorite part of the game. Her character and the song that plays when she is used is brilliant. It is probably my favorite song by the guys at Twisted Pixel and you can listen to it in game or right here. Honestly, Mandy really does get me feeling all randy.
