 On March 9 , 2015 , Stephen DiDuro announced through Twitter that a version of the game for Nintendo 's Wii U console was planned for release on the eShop online store for late 2015 , later specified as August 13 . A demo was released as part of a promotion titled " <unk> @ home " , wherein players were invited to try out several upcoming Wii U games between June 15 and June 22 . On July 28 , however , GalaxyTrail confirmed that production of the final version of the game was taking longer than expected , suggesting that the game 's actual release would be later . DiDuro announced the cause of the delay on August 18 : the Wii U version had been set back by a " console @-@ freezing bug " , which would postpone the Wii U release indefinitely until the issue was fixed . He later explained that the bug had taken so long to detect because it only occurred in retail versions of the console , which had prevented GalaxyTrail and Nintendo from learning of the issue . The bug required a hard reset of the system to address the problem , which could potentially cause damage to the Wii U hardware . However , the bug was eventually fixed , and the game was successfully released on the eShop on October 1 ; customers who had tried out the game 's demo were rewarded with a 15 @-@ percent discount .
