#2 was unable to complete back to title, and I feel there may have been some content in there that is unreachable. Check your interactions zones and see if you missed linking a few (like there's this dude who's pissing or something and i can't click on him) tighten this issue up and 5/5 all around right now it's only a 4/4.
The music in this game is really awesome.
Just played through your newest game. Nice!
But it seems the Aiza sex scene in the "FUCK" section (bottom rightmost) can't be unlocked. I'll look into it later and see if I can figure it out.
