A game designed and coded in 48 hours for the Ludum Dare competition in August 2008. The theme was: The Tower. A tetris-like game with numbers and + and = signs which are combined to form arithmetic equations. Valid equations are formed outward from the equal signs one character at a time, spaces are skipped, so something as strange as 21 0 = 5+ 5+1 will be read as 10=5+5 and 'break' a piece of tower (= becomes $). Equations like 2=2 will get you through early levels, but longer expressions will be helpful as the number of equations needed increases with each level.  Written in Visual C++ Express 8.0 using the Allegro library.  Download: towerpower1.zip Ludum Dare Post: http://www.ludumdare.com/compo/2008/08/10/teenage-mathant-ninja-tower/
