Back in 2013 I tried creating another game using PowerPoint. I used call outs for the images and special effects, and I used slide hyperlinks to create the story.

A year before I was asked to create a drag and drop game, I had been creating a "choose your own adventure" game using PowerPoint. This is the vanilla version. I am in the process of creating this game in Twine and hope to complete it in 2017.
