Thank you for all the hard work and time you put into this game, I can really feel the passion that went into this and it's well deserved. While playing I found a few more bugs? I couldn't earn the Two-Hander skill from the buffet, Pin-Down didn't stay after saying I learned from Beth, Isabelle was missing all skills besides Warmonger. Before fighting the queen I didn't trigger Isabelle's special ending with her corruption over 25 & and the corrupted partner ending to the game.
Hmm... I think I removed Two-Hander (those need to be redone I think. The method I'm using to track them isn't the most reliable)
Pin-Down not staying around is very odd. I swear sometimes RPG Maker has a mind of its own when it comes to skills.
Isabelle has no default skills, she learns them by eating Titan Fruits (unless you gave her titan fruits, then thats an issue)
and yes, the endings are a little broken currently. Sometimes they play nicely but generally they don't :(
