If you're playing the browser version, it's probably related to your internet or your browser. If you're playing in private browsing mode, then your files won't be kept.
The game is not broken, it has been tested multiple times and there's nothing wrong with the save system. The same applies to the downloadable version.
I mean, have you played other games made in Rpg Maker MZ that have a save feature? I don't mean a specific one but rather in general. Most of them allow you to save anywhere and it's the same save system used in this game.
Also, your problem with save files might have to do with the folder where you extracted the game. If you extracted it in a folder that requires administrator privileges, then that's probably why you can't save.
I see. So then, it's either related to your computer and Rpg Maker MZ itself, or maybe it has to do with the folders where you extract/install the games, which is a shame, and I'm afraid I wouldn't know the solution to this problem.
Don't worry, you didn't offend me! I hope you can fix your problem, since there are a lot of amazing Rpg Maker games on Itch that are totally worth it
