In Mario War Escape, the goal is to build a shelter to protect Mario (and possibly Luigi) from Bowser as he flies by. Use the mouse to place the blocks and wall Mario in. Once you are done, Bowser will fly by in his Bowser-copter and spit fire at you. If the fire hits you in any way, you lose and have to try again. If you escape the flames, you move on to the next level. There are 24 levels in all.
