Game works out of the box, but there are some wrong textures here and there and there is one issue which makes it almost unplayable -- you cannot get to the title screen after starting the game, because the menu gets nested within the first and won't return. This prevents you from saving your current game from where you are, and since the game has very spaced out checkpoints (e.g. 2-3h on average to pass to each one) you can't just play it in short sessions, you have to reserve a large interval of time to play it. So buyer beware.
