After reading about the gameplay, story, and the affections system I would like to know a few things (Plz don't spiol it, thx).

1. how difficult is it? I heard of a thing called Mana difficulty, is that hard. I love a challenge.

2. How long should it take me to beat it? to 100%?

3. Im a little worried about the affection system. Is it much easier than it sounds? How many alternate endings are there? How many times would I have to clear it to get all the endings? I know there is always youtube to watch the alternate endings, but I feel like completing as many times as needed to get all the endings and events.

Im ordering it this weekend :) Sadly, amazon only has used games, being in "acceptible condition" Not sure what they mean by "acceptable".

I would like to thank anyone who can answer my questions. Thank you.
