A decent but not great speed run of FEZ in 31:13.1, using a new route that I have been working on for the past month or so. Thanks for motivating me Gyoo when you uploaded a 31:25 a few days ago.
notable mistakes are at:
11:15 when I had to reset the first puzzle room
18:30 when I missed grabbing the edge while behind the level (you should be able to use the vines to jump up, you are behind the level to setup for the invisible platforms)
21:50 when I rotated the wrong way to get to the second time spinner (it should only be need to be turned twice, but I was facing the wrong direction)
24:12 when I missed the the jump to the lighthouse (you jump after the edge, and grab the last block of vines on the edge by the lighthouse door, saves .5 seconds when there are no black holes in the way).
These mistakes total over 20 seconds, showing that sub 31 is possible on current version.
