This is the second of several games produced as a 3 week "challenge" called Game Slam at Ninja Kiwi. The idea being that each team of 2 creates something original and complete inside the 3 weeks. This weeks game is Battle Blocks Defense, by Tosh Baird and Warwick Urquhart. Battle Blocks Defense is an inventive puzzle/defense hybrid where puzzle pieces are placed on the grid to act as shields, attackers and energy generators. Combine like-coloured pieces in a 3x3 block to build a mega tower. Only the right balance of towers, quick thinking puzzle play, and nerves of steel will see you through all 50 waves of enemy assaults.
