Close: it's endepis (end episode)

As for highscores and cinematics, I'm afraid that's only possible if you make your own episode file. Episode files contain (as far as I know) the picture and logo for use in the menu, and the links to A) the first level, and B) a cinematic or the next episode.

The "endepis" setting merely triggers the level to say to the episode file "Hey, buddy, it's over, what's next: cinematic or a new episode?" However, the Home Cooked Levels episode has neither, so it skips to the main menu.
