Minigame update - Poo-Yo Poo-Yo Tetwis

New minigame has been added - Poo-Yo Poo-Yo Tetwis.

This is based on a standalone game I had made before which can be found here: https://biancagames.com/other-random-games.htm

Unlike other minigames currently existing in Risette Escape, this one actually shows the current character. While I intend to favor this way of doing it moving forward, I also don't intend to change the older ones as they had storyish reasons for being specific to the characters they were associated with.
