Hey guys,

A friend and I are keeping a video log of our progress on a puzzle game we are building called Mind. This is our first vlog in which we discuss the elements of a good puzzle game. I thought it may be interesting to share the video and gather the community's opinion on such a topic.

So what do you guys think? What are the core elements that make a puzzle game fun, addictive, and rewarding? Is interdependence really a core element, or were we off in our observations?
