Like the other two sites, you're left to your own devices and patience as you try to "click around" the scenes in the proper sequence in order to cause events to unfold, and the story to be told.
And if that's not really your thing, thanks for visiting anyway. For your trouble, here's a cool new online basketball shooting game that even I can play well. You first practice and then shoot against other real live players online. You score higher for clean baskets and quicker shots. Nice reward for those students who finish their work early.
