Nearly everything, after installing Direct Music and dsound (via winetricks for example). Playing (performance is good), saving, loading, enjoying the game is totally possible.
What does not
Spooky has no voice, I think on Windows she has.
What was not tested
Playing through the whole game. Played around 300 rooms in one run, no crash.
