The premise is that there are these bad guys called the INKT corporation that have stolen all the color out of the world. Your job, as de Blob, is to absorb color (red, yellow, blue) and repaint the world while fighting off the INKT soldiers. You can also combine colors to get purple, orange, green, and brown. The different colors have different effects on the world, and the more colors you use to paint certain things, the more points you get. There are cut scenes between levels that document the INKT minions responses to your actions which are TOTALLY hysterical.
Anyway, for younger (less than 9 I'd say, though artistic kids who are older and love art would like it too I think) girls or boys, I think this is an AWESOME game.
