All right, here you go.
The main physical symptom is that debug builds simply crash trying to load the mainhall, whereas non-debug builds load a black screen. (I note that in a case of good design or simple luckiness, when that happens clicking anywhere results in the option to exit the game. Kudos to somebody.)
(I also note it may not be playing the full opening video anymore. Or is it supposed to skip the "SPPPOOOONNN!" part after the first time?)
