Chaos Theory is another of the smaller games to get boosted into the public eye by Steam. We’ve had Gumboy, Gish, Audiosurf and the slightly unjustifiable Ninja Reflex, and now it’s Chaos Theory’s turn to look slightly awkward rubbing sholders with Call of Duty 4 and Chuzzle Deluxe. The idea is to get particles of one colour to orbit their corresponding Collector nucleus. You do this by propelling the particles towards them at the required minimum velocity. Your tools are charged poles which you can polarise to attract and repel particles, gathering posts to fire them from, and rotating deflective barriers to bounce the balls in the right direction.

This all sounds like classic casual action, but BlurredVision make the brave move of alienating bored mothers with clinical grey levels, odd attempts at art deco elegance, and overtly scientific action. This nerdy edge is perfectly acceptable tous – in fact it’s nice not to have a cutesy chipmunk telling us we're awesome every timewe complete a level for once – but we can’t help but think that avoiding the approachable colour schemes of the genre will only hurt the game’s sales. That said, Steamworks achievements add the occasional and pleasant surprise when they appear in the bottom-right corner of the screen.

Where Chaos Theory struggles is the consistency of its levels. There’s a good balance of skill, puzzles, and trial and error, but for every level that gives you the thrill of solving a puzzle – or “buzzle”, as we professionals call it – there’s one annoying level in which you’re just clicking without skill or thought. Persistence pays off though, because Chaos Theory pulls through a level 30s lull (you have to complete levels to progress, although you have a limited power to skip them – level skips are earned for completing sets of levels) to provide some genuinely entertaining and lobe-flexing levels.
