I'm also one of the lucky few who got to play it already and my advice: curb your enthusiasm. As TD mentioned earlier it's focused on Hana (REALLY focused) and even though Hana is my 2nd or 3rd favourite character by the end I was tired of the date :]. I'm pretty sure that most people will love it (considering Hana is overall the most popular girl) but IMO it's the worst update so far (which doesn't say much considering how high quality their updates are, it's still great but less great IMO).
In the end listening to me or Caz is pointless, you will have to play it yourselves and judge.
