What does not
Nothing I noticed.
What was not tested
Nothing, played the game from start to finish.
The same applies to the second episode. Wanted to get the native version, but apparently there's no way to get it now, so I bought it through Steam. The Linux demo actually worked worse than the Wine version, but I didn't really try to do much about it.
