Save1- go ahead and use death potion on jimmy to see Iris losing scene
Scene2- Is a "If" content that you can find in the main menu on the bonus part with the new character (the new priestess)
and that is it for the 0.80 version.
I have not seen any one time scenes on this save so you can use it to see all of the content of the game (as long as you have patience to go around without an objective) although PotionMaker is bugged (at least I believe so) so you cant see her content with it
Try losing to monster with hearts above their heads, going to the dark elves camp, or just stroll around the city.
