** PLEASE MARK SPOILERS **
I just played through on the PS4 version and got to 200%, really enjoyed it. I didn't look online at all until I was around the 160% mark and then I was starting to get really frustrated with not understanding the alphabet plus a couple other things and just decided to look online for a little help. I probably never would have figured that out on my own, the solution was incredibly clever and well-hidden. But at the same time it has got me thinking about how the Internet can take the fun out of a game. It can sometimes be really hard to force yourself to think through a puzzle when you know you can open up your phone and just Google for a solution in five minutes. With most other games, the solution turns out to be completely ridiculous and unfair so you're OK with doing that. But in the case of Fez most of the solutions turned out to be actually reasonable once I understood them.
A lot of Fez's harder puzzles were apparently designed to be worked out by the community online. But from what I've been able to read, the community got that all done within one week of the game's release. Anyone who played the game after that period (which I'm going to randomly guess is 80-90% of the game's players) can't get that "perfect" Fez experience of working out those solutions along with the rest of the Internet. I'm a little sad I missed that. I really hope Fez 2 get un-cancelled and then I could go through that whole process with the sequel.
Anyway, how far did you get with Fez before you looked online? Did you regret looking online or were you OK with it?
