I guess the items you mention are needed for quests, like the letter you mentioned from the abandoned hideout with skeletons. Sometimes you can pick them up before getting the quest. I made it possible so players wouldn’t need to visit same location twice just to fetch the item.
Most likely you hit the spot in vagabond’s quest line where you need to find who’s wiling to but the monster girls from them. Ada suspects the baron. So, just get to mansion’s second floor and find a monster girl there.
Extra stats are hidden in classic RPG Maker’s layout. Speed is the ability to do something before the enemy. Crit = more critical hits with greater damage. Dodge = chance to evade a physical attack.
No, Yorna won’t have customization aside from the on-map Ada’s picture with currently equipped dress. Since adding variety must affect scenes, each small change in Ada’s appearance must be reflected in all scenes. This means more frames, and this quickly spans out of control. It’s not impossible but with the current H scenes system, it’s not viable to due a huge workload. Plus, I think more people will appreciate animated scenes - working on them right now for the future project.
Yorna won’t have DLC packs because v1.0 will go public and remain free after that. EX version will receive new H scenes and a few mini-dialogues with monster girls and go on distribution platforms as I already mentioned in my dev plans post. Locking DLC behind a EX paywall is a dick move.
NW.js shouldn’t react to any kind of game interaction unless you made some changes inside the code and/or saves via cheat engines or something like this. If it’s not the case, download the last version from my Patreon and try again. Just checked the letter and it works fine.
