An interesting, but very demanding, musical game. If you do not fear frustration.

Simple, psychedelic and effective, this is how one can sum up Cosmophony, the latest rhythm game to hit the Wii U's eShop catalogue. Its gameplay mechanics are very well implemented, which makes for long hours of fun topped by its sometimes too punishing difficulty level.

Had the game been a tiny part of a greater whole it would have worked. But as it is, and particularly on the Wii U, Cosmophony ends up playing like a demo, stripped of its powers to sustain by its confused design, lack of content and its impossible level of difficulty.
