Feed Me Oil 2 is a great puzzle game from Chillingo, publishers of other iOS favorites Cut the Rope and the Anomaly series. In the game, you have to channel oil into monsters in a wide variety of environments, using many tools and techniques to get the slippery substance where you want it to go.
The game was recently updated with an all-new chapter for you to explore. You can "collect the eggs tucked away in your favorite Feed Me Oil 2 puzzles" to unlock this chapter, according to the update notes. Chillingo has also changed all the gross oil to be "delicious molten chocolate" for a limited time.
You can grab Feed Me Oil 2 at its new, lower price of $0.99 on the App Store.
