I absolutely love that game. Still have to finish my second playthrough.
Gamepla mechanic is just basic stuff but the whole story and atmosphere is the best since Bioshock!

Also liked the first Alice. Gameplay mechanics and controls are rather bad but its the atmosphere that draws me in as well and the Soundtrack is gold! So creepy, tense music. One of the best game soundtracks ever.
My favorite songs of the Soundtrack, give it a listen:
