hello, i have a menu screen on the first login to the game. In the meantime I want it to check the save data. For this, I don’t need to keep this data in character. Do I need to keep this query in the menu widget? for example there are 10 levels, the user opened 5 levels, should I keep it in the mainmenu?
You need to use the save game 
yes i know that, but do i have to save from “game mode” for save data? I have mainmenu “GameMode”. Does it make sense to keep save datas from game mode? I don’t want it to reference the character, I want it to reference the gamemode 
You can access it from anywhere you want to. You can get it from the game mode or the menu system. Really up to you.
