World of Goo, 2D Boy’s gloopy-gloppy indie puzzler, has dropped to 59p for one day only to celebrate Valentine's Day.

The multi award-winning game has you building towers and bridges out of sticky, gelatinous blobs, hoping to strike a balance between making a sturdy enough structure to reach the exit and keeping enough blobs free to escape.

Once you’ve beaten the game’s many worlds and levels, you can wile away your days in the Gooey sandbox, trying to make the tallest tower out of globlets, and beat your friends’ best heights. The game uses Apple’s Game Center for achievements and global leaderboards.

We were impressed with the game in our review, giving the app a Gold Award and calling the charming, smartly designed game, “the best physics puzzler available on iPad.”

Get in quick, though - World of Goo is only on sale today. The iPad-only puzzler can be yours for 59p / 99c / €0.79c until midnight, when it will rocket back up to £2.99 / $4.99 / €3.99.
