Hey orange~,
I really like Fear & Hunger: Termina so far! However, I'd like to suggest a feature: "Field Saves". Essentially, let me be able to save the game from the menu while exploring Prehevil temporarily because it really sucks to lose a lot of progress because you can't continue playing for whatever reason.
This savefile should automatically be deleted after loading it 1 time or if the game wasn't shut down properly (that would prevent save scumming)
Many rogue-likes and rogue-lites use this save system (e.g. Shiren the Wanderer and Pokemon Mystery Dungeon to name a few).
