thank you.i finally give up on it.i've tried to fix it for several days
No problem, tbh there are two ways I usually play games made in RPG MV (since I use a Mac) - I either make a small local server in Python using the 'www' game folder, or play with AopAop on my Android tablet (which has a keyboard attached, using any Bluetooth keyboard will work too!).
Obviously, watching gameplays is not the same, but since the games are mostly story focused it's still very close to actually experiencing the game.
