Script Saving – Spoiler alert!

[Andari]

Hello all!

What I want:
Disable quick save and autosave when exiting (So the save and exit should not appear), and the only way to save would be to interact with some water / Fountain (etc). How is it poosible to disable the saveings? I want to use an examine area, so when touching it (would exactly be where the liquid area), a message (like "state saved", only bit cooler ) would be shown, and a drinking like sound would be played. Also a splash could animatet.
I want also: When an enemy kills the player, the game would reload From the latest save-point, and (only adter death) a message shown ("Sometimes when I drink, I have dreams where I die. They Feel so raelistic..."), so in the story, every death would be a dream... How is it possible to set the message shown only avter dieing?
