I bought FEZ when it first came out and played it fairly zealously for a short burst of time before becoming overwhelmed with work and other responsibilities.
I returned to it some time later, determined to not look anything up online unless I was absolutely stumped for two weeks or more.
I eventually got to 32 golden cubes and 27 anti-cubes.
I had not been able to figure out the alphabet yet, so finally reluctantly looked it up. It made sense in retrospect, but I have to say that I would never have figured it out on my own, unless I started a new save game (thus being able to remember which room I found the writing cube artifact in and being able to scour it for clues).
I translated as much text as I could find, so was able to read the security question in the candle room below the waterfall, which appears to be the only place where reading letters is necessary to acquire a collectible (apart from the Tome possibly being a clue to the monolith). Happily, the numbers had been much more straightforward.
I also looked up how to get the four-sided clock's last two anti-cubes.
I ended up using flying to reach the few treasure chests that you're meant to use the treasure maps to find hidden platforms to get to as well as the skull artifact, which was my last artifact acquired.
I have to admit that I finally just looked up the solution to the security question and the black monolith (sad day), however this brings me to...
I have 32 gold cubes and 31 anti-cubes. I have (I believe) 3 heart pieces. The only two rooms that are not outlined in gold on my world map are:
- the island with the 64-cube door (white outline plus 'Secret' icon) and
- the telescope observatory interior (white outline but no icon on the map) I got both the heart piece and anti-cube in the observatory, ages ago. What else is there in the observatory? I've stared at the patterns in the bookshelves below forever, but can't seem to make anything intelligible out of it.
I've also tried about every key combo that I could think of on the 64-cube door island to no avail.
I'm at a loss as to where I'm meant to find the last anti-cube. Any suggestions, friends?
