I don't think anyone was really expecting Polytron's FEZ to be updated, well... ever. One could argue the 2012 platformer (2013 for the Steam version) has well and truly had its day in the sun. That didn't deter developer Renaud Bédard from pushing out a huge patch yesterday, one that's apparently been in the works for over a year.
According to a post on Bédard's blog The Instruction Limit, he started plugging away at the patch in 2015. Specifically aimed at the desktop versions of the game (Windows, Mac and Linux), Bédard essentially uprooted the guts of the game and gave it the spring cleaning of a lifetime.
It is also intended to be the "last update", something Bédard explains in more detail in the Steam announcement:
Since I shipped FEZ 1.11 I had little intention of making additional fixes or features to the game because I simply don’t have the time with a kid and a fulltime job... and working on FEZ is getting old after 9 years. So I did want to address problems that people have with the game, but I don’t want to do it for the rest of my life. I had spent enough time away from the game that I was somewhat enthusiastic about coming back to it, especially if it’s at my pace, and that it’s my last time doing so.
Uncertain of where 1.12 would end up, Bédard decided it'd be best to keep things on the down-low:
So I didn’t announce anything, I didn’t announce a date, and I slowly chipped away at making this humongous update to FEZ. It’s been in beta-testing with an army of fans, speedrunners and friends since late January 2016 and over 120 bugs have been reported and fixed.
A lot of the changes are somewhat technical -- and numerous -- so I won't dump them all here. But, if you're interested, I highly recommend reading Bédard's post, which goes into amazing detail about everything new in the update.
