Beat the game a total of 3 times now, pr fun, its simple, some bugs (obviously) but my runs have seemed to be rather fine. I'm still missing scene 7, but I've gotten pretty much everything else. All abilities, All weapons, I think all hp buffs and even beat the game w/ the "NG+" new character, as in the bandit girl. If you play NG+, press Down+Z to swap between Lily and her. She appears to have no (new) scenes and you cant gain lust while bandit girl. All CG's are pr much identical to the first runs. It was interesting to say the least but nothing too crazy.
For the common questions I'm seeing here are the answers.
>Map 15 is accessed via using the potion you use to go to heaven / hell anywhere outside of the shrines or what have you
>All abilities are easy to find outside of the one requiring the block puzzle. You'll know if something is in one of the maps if you see its percentage not being 100%
