 Bédard planned to leave Polytron after finishing Fez to experience work with a full development team , but stayed to port the Windows release before joining Toronto 's <unk> Games . He credited the game 's long development cycle to his own inexperience in game development ( compounded by the team 's small size and difficulty in setting reasonable milestones ) , the game 's scope , and Fish 's <unk> . Fish had hoped that players would discuss Fez 's nuances online after the game 's release . Players collaborated online for a week to solve the final " <unk> " puzzle by brute force . Ars Technica described the apparent end to the game 's harder puzzles as " <unk> " , but Fish told Eurogamer in March 2013 that hidden in @-@ game secrets remain to be found .
