With a steep difficulty curve from instant play, Super Robo Mouse can easily put off players not use to the challenge. No variety of music, mid-game pause function and general lack of sounds is dampening, still with 20 levels across 3 worlds including creative mechanical bosses and the cheap entry point you get a reasonable amount of content. For those that relish such demanding gameplay, this fits the bill exquisitely.
Super Robo Mouse doesn't deliver the goods. There are other challenging, twitchy action titles on the Wii U eShop that provide a stronger presentation and are more fun to play. Save yourself a broken window and lost controller and spend your money on something else.
