Note: The following may constitute a (very mild) spoiler for FEZ’s math/language.

To be honest I had all but given up trying to be useful about the mathematics. I’m not much of a numbers person. I regularly stumble over adding a number to the result of a twenty-sided die when we play Dungeons & Dragons.

However, as it turns out, the trick to cracking the numbers isn’t really so much about your mathematical chops as your ability to notice things.

(Likewise the Rosetta Stone, which may not be obvious as such, since it doesn’t quite do what the original Stone did.)
