save files auto reset every few days is that something that should happen for the free play on itch.io web play
Yes, the WEB version's save files are stored in the browser cache, so we cannot guarantee their safety at this stage of development. If you want to keep your gameplay stable, we recommend downloading the PC or Android version of the game. In them, the save files are stored in system folders, which is quite safe (unless you reinstall the operating system, of course). Plus, they will be compatible with later versions :)
