I've been looking forward to this one: The Will of Arthur Flabbington by Gugames. I'm a great fan of Guga's games, and this one is no exception. The game is made in unity, and it's a demo of a larger story (I hope). If you have played any of this author's games before, you know you can expect humour, solid and original puzzles and fluid animation. In addition, this game features very good voice acting, as well. Highly recommended!
