## Why It's Good For The Game

This PR makes getting the “Ordeal of Sisyphus” extremely pointless by
teleporting carried boulder and spessman back to the Lavaland. In my
opinion, this feature is funny and suits the spirit of this achievement.

## Changelog

add: Added a short scene when getting an Ordeal of Sisyphus achievement.
