This seems more like a proof-of-concept for an educational game. As far as I got there wasn't really a story. Your choices consisted of whether or not to use electricity (a precious commodity living in a van with solar panels) to do things like make coffee, or wash dishes with hot water. Then you had to answer math questions regarding how much power it would take to run the selected appliance.
Again, this seems like it was specifically built for an electrical engineering class. Since I'm not an engineer I didn't really have any clue what I was doing and the game didn't educate you at all that I saw. This would be more like the final test after the lessons.
Could be a lot of fun if you are in to the subject matter, but didn't really do it for me.
