Kinda sad that she didnt get one

Unlike the first two volumes it doesn't state, "adult version" so will this require a patch?

The game is really short compared to the volumes, and I don't know if it just installed wrong but the 18+ patch isn't working.

Why at the end of Vol.2 (showing what will happen in Vol.3) Yuusuke says: "Why did I think I was the only one able to walk among them?" Anyone would say that this means that in Vol. 3 there was going to be another person "immune" to the zombies , that is, like Yuusuke, but in the end nothing happened. Why? Why was Vol. 3 shorter than Vol. 1 and Vol. 2, considering they could have added so much more awesome content?...

No spoiling since I haven't played 3 yet I bought vol 1 just to try it out, actually really liked the apocalyptic theme. First time for a visual novel for me. I just finished Vol 2 and was excited to try 3 but checked reviews first. It seems there's quite a few people who did not enjoy 3 as much as 1 and 2. A bad ending is enough to make me hate a series despite being good in the beginning and middle. Without spoiling anything, I wonder if I should just leave it at vol 2 and leave my imaginations to what...
