yes it would allow the player to modify or mess with the files.
but imho that’s not something you should really try to control.
as long as you put the files in a folder relative to your game the user should not break them by accident.
i would, at any case, add logic to deal with a missing file. to make your game more resilient to any disk accident.
the engine provides a way to obtain a folder for the “saved” stuff, including configs and savegames.
saving to that folder would make it so that steam could persist those images to the cloud too.
trying to control the user doesn’t seem like a useful thing to me. and as i user i don’t like those practices. if someone wants to mess with the game they will do it anyway. it seems like a waste of energy to me.
