* Letter balls fall from the top, piling up in a 2D physics simulation * Don't let the letters pile too high! * Spelling words calls in a wrecking ball which explodes the letters and scatters the pile to recast the playfield * Letters from mis-spelled words turn to "Rocks", immovable obstacles which take multiple hits from the wrecking ball to destroy * Power is earned with each spelled word, and when fully charged, power ups can be used which help get out of tight spots
