You can unlock the final area with 32 cubes collected and I achieved that in about 6 hours of total play. I have many more cubes to collect and plan on doing that here and there over the next bit. The ending sequence was really interesting and I don't want to say much to spoil it but I will say that it was unique and thought provoking.
After you...
Thanks for pointing out that 32 cubes is sufficient to reach the ending sequence. Since it got released for Linux and runs more smoothly than in Windows, I set about playing earlier today. The game is so expansive, the maps so large that I wondered if the game actually had an end.
This is on my ever-changing list of 20 best games of all time. From the first magical moment when the 2D world spins around to become 3D, Fez was nothing but a delight to play.
Yeah, I wanted so share the 32 cubes bit because I wasnt sure when the game would end either. But when you get to 32 the game tells you you can enter it, which is nice.
