What seemed like a gag in the first instalment has long since become a genre in its own right. Over 30 missions lead through playgrounds, suburban houses and industrial plants, each time a little bigger, a little dirtier. Instead of battles or quests, there are lists, progress indicators and that characteristic "ping" when an area is clean. That's the sound of order. And the longer you play, the more you realise that FuturLab doesn't mean the game as a joke, but as an amazingly precise simulation of human satisfaction.
The tone remains pleasantly absurd. Whether you're cleaning half a city in Sponge Valley or washing down a gigantic dam wall in Power Falls, the game never takes itself too seriously. The humour comes from the discrepancy between effort and result. There are new tools like the surface cleaner, soaps for particularly stubborn stains and even multi-stage jobs that expand as you progress. And of course the base, which you furnish as you wish - but only after you have cleaned all the furniture. Consistency has its own charm here.
