Most things - the game is very playable, especially if you have a registration key already...
What does not
Web links in the pre-registration launcher, along with the ability to buy a registration key.
A few minor problems with the graphics: object which should be partially off-screen (bouncing tiles or the text in the demo) are fully invisible, some in-game dialogs flicker as they appear on-screen, and the goodbye screen doesn't scroll smoothly.
A few sounds are slightly different than on Windows.
What was not tested
Purchasing the game as a "gift" from Alawar's website might be a workaround if you need a product key, but I didn't try it.
