1. How difficult can the game get when trying to fully complete it?
2. Does Elsie have any permanently missable content, where the only way to try again requires deleting my save file?
3. Is this game the same on all platforms, and does the Switch version have in-game achievements? On that note, I see the Steam version has way more achievements than the PlayStation version, and I don't know if that means the Steam version has additional challenges or not?
4. Does this game have any promotional or limited time bonuses, or anything unlocked by having save data from a different game?
