Super Mario Summary is a new flash game that reimagines every level of the original Super Mario Brothers for NES. What makes it interesting is that each the levels has been condensed from its original length down to a single screen's worth of gameplay.
The first level is a piece of cake, but it doesn't take long for even the most seasoned Mario gamer to start pounding his keyboard in frustration (ahem). Created by Johan Peitz.
