i found a bug where the audio keeps goin back to 100% when fighting enemies, no idea why it is happening but i need to lower it everytime because the game audio almost blows my ears, and also why tf is the game window so small bruh
Because that's how RPGM games are. I think F4 or F11 will make it go full screen. If not, try alt-enter. Save your game if you're in the middle of something before you do that. One of these buttons can reset it back to the main menu. I think that's F5, but don't quote me on that. It differs based on the RPGM engine.
As for the game, as with all of Gyu's titles, it's made with spaghetti code and thoroughly bugged. Nobody knows if Kagura will be able or willing to fix the bugs. Maybe they'll just ignore it, as with Messiah. m1zuki's fan translation which exists for half a decade already, has all the bugs fixed. Its only downside and main difference between it and Kagura's version, is that its CGs are censored.
m1zuki's 5 year old fan translation: No bugs, game's playable and probably won't crash, censored CGs.
Kagura's official localization: Bugs, game will crash until (if) fixed, uncensored CGs.
That's the gist of it.
