First, there is absolutely no reason to save and reload, since you can restart the pizza minigame, like any other minigame, simply by pressing the TAB key if you are not satisfied with the outcome. Second, my mod also allows to rollback, but that's beside the point (see reason before).
I made it the second best outcome because I don't want it to be a money cheat. It is still sufficient to beat the main story, and I think there must at least be a hint of a challenge for that. Otherwise, just open the console and type "unlock_all_scenes()" to get everything in the cookiejar without having played a single minigame
