I played this forever ago, around when it first came out, both the OG and Weekend. Is this version worth playing as well? What's different about it? What's it add? How's the translation?

Satori's been the hardest boss for me to deal with, her having a Elixir and Petro Cloud. I've dealt with Extra but Perto Cloud still gets me, I'm using Reimu's Evil Sealing Circle and Sanae's resistance but they don't seem to work. Is there a defense for Petro?...

游戏里面的语言设定怎么按都只有英语，怎么才能切换？

I need it in order to craft Soli Deo.

Been playing the game for quite some time now and have hit a point where there's literally nothing I can do to progress without leveling. Problem is for the life of me I can't even get passed the main "bosses" that guard the real boss to raise the level cap. Been looking online for ages and can't find any guide at all on these enemies....
