Ghost of a Tale is an upcoming game by Lionel Gallat, who was, among other things, the animation director for Despicable Me and The Lorax (which explains the gorgeous graphics and animation!). Ghost of a Tale takes place in a medieval animal world reminiscent of the popular young adult novel series Redwall. The player controls a small mouse and progresses through the game in the fashion of a classic action adventure game.
Ghost of a Tale is being made in Unity and is slated for a 2014 release.
