Please Download this game for less lag (downloading also lets you make more walls) This game is an interactive environment where you can drag building materials and make structures, turn the walls by clicking them and pressing the left and right arrow keys, click them again to deselect them. When you're done building, press start, and the physics engine will kick in. Chose your weapon type and explosive power on the panel to the right. Press the spacebar and an explosion will happen on your mouse pointer. In the case of a cluster bomb, the bomb will steer towards the mouse pointer and detonate when it hits the ground. Comment and love please! It took me a long time and some serious debugging =)
