Hey, do you remember Fez [official site]? You know, the clever little platformer where you could rotate your 2D world on a 3D plane to solve puzzles? The PC version may have released all the way back in 2013, but Fez has just this week, quite secretly, gotten its final patch.

The patch had been in the works for about a year as the game’s sole programmer Renaud Bedard (who is now with Eidos Montreal) slowly chipped away. The massive fix was then tested by fans, friends, and speedrunners starting in January 2016.

Bedard discussed his plans for the unexpected patch on his blog:

“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.”

I’d say it’s a worthy final patch, as it fixes up a number of key issues that improve performance quite a bit. The fix also improved controller mapping, graphics issues for both low and high-end PCs, and even threw in a speedrun mode. You can check out the full patch notes here, though they do get quite technical. Don’t say I didn’t warn you.

You can try FEZ for yourself either on Steam or GOG for £6.99/9,99/$9.99.
