Personally I adore how the characters play out and all of them feel unique. While there is a challenge for figuring out how some characters work (Dr Akira going to the right door and not the left) the post game over tips are most certainly very helpful (outside of night 6's, but that's a difficulty factor) if there's one thing I'd like to see, it would be some kind of "daytime" mode of sorts, where we can appreciate Mina's own growth without the worry of all the other girls going for her.
