Playing it on the iphone now.
No intro - what the f***! the intro was one of the best bits of the original
Poor translation of the iMuse system - This was explained during the trailer and that is the limitations of using digital music but the music when swapping between rooms just isn't seamless as the original
Massive lag when exiting rooms - Can be really noticable when playing and does take you out of the game
I'm sure some of these will change with updates but it really is a quality game. Surprised at how much i remembered from the last time I played
