And as the levels advance, the obstacles only grow in size, sometimes literally.
Since all of the goo balls sport realistic physics, if you don't build your gooey connections thoughtfully and with respect to gravity, they will very likely come crumbling down and you will need to begin again. Take those first few stages, for instance, when the only goal is to reach the end without toppling your structure. In fact, it's usually decidedly difficult. You exit the levels through pipes that suck the goo balls in and off to the next puzzling hurdle, a task not always easy. You'll learn the basics right away since you'll be required to construct a gooey pillar reaching to the stage exit up above. There are more than four worlds, each housing a chunky batch of unique stages, most with highly different objectives that always come back to very smartly utilizing the strengths and weaknesses of the goo balls. The graphical and aural finesse completes the package, but World of Goo's winning challenges are its finest feature. You'll hardly believe you're still playing a WiiWare game.
Wait until you happen upon the windmill level and come talk to us. Goo features a sensational visual style that looks inspired by titles such as Loco Roco, but 2D Boy has taken the presentation to the next level with fabulous designs and animation. What you will find in abundance, though, are gorgeous settings, serene music and funny sound effects from the goo balls. These story shavings are slim, but this isn't really a game about a great yarn. At another, he promises that there's a big change waiting in world four - and fear not, we're keeping the spoilers to a minimum. At one point, you will stumble upon a message in which he unleashes a diatribe on the fact that the title doesn't run in high-definition. You won't really know what's going on in this goo-filled world, but there are messages left behind by the Sign Painter, whose philosophical commentaries blend together with surreal out-of-game observations.
