I love concepts that take the theme of the jam and flip it on its head! That you're connecting people to each other through messages doesn't mean you're not feeling alone yourself. The chess game was a really nice touch - especially since you can walk on the table and knock over a bunch of the pieces. I also loved how the tutorials were shown as post-it notes to remind the hypothetical employee of their work. And the vicious cycle continues...
Bonus points for being able to do a barrel roll in your sleep!
