Not long after revealing that World of Goo for iPad has moved over 125,000 copies since its release last month, 2D Boy has discounted the fun puzzler to the low, low price of $1, much cheaper than the $5 it usually sells for (or the $10 price it launched at).

This deal ends today, though, as it's meant to be a sale for those "awaiting a cold and cheap Valentine's Day". Those of you who don't have an iPad can still grab more expensive version of World of Goo on WiiWare, Windows, Mac, and Linux.
