The amazingly innovative "World of Goo" deserves credit for drawing gamer attention to the burgeoning independent game developer scene in 2008. The physics-based game challenges players to build structures like towers and bridges out of goo balls to herd their goo family to an exit pipe at the end of each level. Gravity, and the terrain itself are the only enemies in the game -- each stage in "World of Goo" is a logic puzzle in gooey architectural design.
"World of Goo" oozes style and charm and actually has a plot tying together its delightful puzzles. The real draw here is seeing your precarious constructions hold together or sway back and forth as goo girders struggle to hold together. While plenty of "World of Goo" levels can be completed in just a few minutes, it's definitely more challenging (and rewarding and creative) than the average iPad game.
"World of Goo HD" currently sellsfor $4.99 in the iTunes App Store.
