Fez is a good game. I really enjoyed playing it. The gameplay is fluent, the puzzles are well-made, but - what's most important - you got a pretty big world full of secrets to explore. However, I was rather disappointed when I tried to play this game on Linux. Steam has got a Linux version, so Gog loses quite an edge. If you expect that you want to play this Game on Linux at some time, Steam would be the better option (except if Gog gets a Linux version).
