The levels themselves start out fairly easy, making the path to success pretty obvious and able to achieve within the first try or so. But soon the puzzles become quite complex, with large areas of white tiles and a few black tiles scattered about in order to make things interesting, or twisting paths of white tiles with holes and black tiles strategically placed on the way. A counter at the top of the screen counts down the number of tiles left to remove. That little red tile never looked so far away.
Similar in concept to Kyle Gray's Flip Out, as well as to Aqui Griffin's enQbate, an entry to our "GROW" themed competition in 2007. A couple months later, Damien Clarke's Bloxorz brought the puzzle game into the 3rd dimension and added the rolling box. The presentation here is very similar. With 30 levels to roll through, On The Edge will keep you scratching your noggin for a while. Roll on!
