Super Collapse 3, for the most part, is just like the original online time-eater, but a little bit more, and a little bit better. They've taken the original premise a couple steps further by adding a couple of different types of game-play, but they also leave this gem unaltered for 'quick-play mode'. The DS's touch-screen controls are a much more efficient user interface (expect to increase your level-advancement by 50% by NOT using a mouse) even though the playfield is notably smaller than a 'standard' PC monitor. Ignore whatever trepidations you might have & give it a try; the only thing you have to lose is free-time... :D--Warning: HIGHLY ADDICTIVE!--
