<em><b>The 3D Tetris game for flatlanders</b></em><br/>
<em>Version 0.0.1</em><br/>
<br/>
BlockOutLine is the side-view version of the classic <br/>
<a href="http://en.wikipedia.org/wiki/Blockout">
Blockout</a> game. Provided with multiple facades as <br/>
hint, the player needs to interpret these 2D <br/>
projections and rebuild the 3D scene in the mind. <br/>
<br/>
The four panels from left to right show the back, left, <br/>
front, right views (orthographic projections) of the <br/>
cubes respectively, where solid lines represent visible <br/>
edges and dashed lines represent hidden ones.<br/>
<br/>
The goal of the game is to form complete layers and <br/>
gain score points as high as possible. <br/>
