User Summary
The Liar Princess and the Blind Prince is a fairy-tale themed action adventure in a 2D platform style, where the player plays a giant wolf who can transform into a princess and who must guide a blind prince through the dangerous woods in order to meet the Witch.
The player switches between the invincible wolf, and the tiny princess, and can give the prince a few instructions on when to walk and not.
The game was released for Switch, Playstation 4 and Playstation Vita, both in a physical media and download for all three systems in Japan, on 2018-05-31 (source: publisher's website). In the West, the game was released on Switch and Playstation 4 only, on 2019-02-12 (source: Wikipedia) with the Europe version on 2019-03-01 (source: PEGI), probably (guesswork) only as a downloadable content, i.e no physical medium.
The ratings for this game are interesting: Japanese rate this CERO 12, American's rate it as ESRB E 10+, but in Europe, the game is considered as containing "scenes of bloody violence in an arcade setting" and is "Not appropriate for persons below 16 years of age." Quite hilarious, as any consistency in this regard would easily banish every single fairy tale in the history of mankind.
