Here is a link with downloads for every level, excluding intro cutscenes (good for individual level runs/practice)

Also included maggot fight save for Dr Jell's, platform section in joyfruit, and Boss fight includes NPC to skip the pie baking.

To use them make sure you have a save file in the 2nd save slot (NEW GAME WON'T WORK) and paste the save files over top of your Hell Pie saves located in C:\Users\User\AppData\Local\HellPie\Saved\SaveGame. (To easily locate you can paste %appdata% in your explorer bar, push enter, and go back to the local folder as it defaults to appdata/roaming)

You do not need to close the game, just go to main menu and paste the save file.

[Post Boss - All Horns is on save slot 3, Post Sashimi is on Slot 1]
