They’ve done it again!  Chillingo –  makers of some of the most popular games in the app store such as Cut the Rope and Angry Birds –  have introduced a well made, addicting, and very fun game.  Its title: Feed Me Oil.  Feed Me Oil takes elements from a few popular games and mixes them together.  We all remember one of the original iPad games, Enigmo, where your goal was to get droplets of water into a bucket of the same color by dragging elements onto the screen.  Feed Me Oil employs that same premise – though a better made physics engine forces the oil into clumps as it touches to act like a heavier material.  The elements you have to play with are also much more interactive.  We also can’t forget a fairly recent popular game to the app store, Where’s My Water?  This game has a similar liquid clumping physics engine, but instead of dragging elements onto the screen to guide the oil, in Where’s My Water, you manipulate the landscape of the level. Put the Enigmo element bank and Where’s My Water liquid physics engine together and you have Feed Me Oil!

Main Screen
Believe it or not, the starting screen is tougher to navigate and figure out than the game itself.  Luckily, the Start Game area is the largest – which will allow you to get playing fast if you’re not worried about any of the other setup elements.  If you are, you may want to read the rest of this section.  The obvious linkage to Facebook and Twitter is shown through their respective symbols on the top right.

However there is also a large ‘Crystal’ button.  If you push there, a whole slew of options will appear on the left hand side of the screen.  Crystal is a social game network, just like Game Center from Apple.  The reason this is confusing is because Game Center is also built into this app.  I would enjoy seeing app developers begin to accept Game Center as the iOS gaming standard, instead of confusing apps with multiple social gaming platforms.  As a general rule, I put a strike against any app still employing a separate social gaming platform. The orange, purple, and green buttons along the bottom will link into Crystal’s Gifts, Achievements, and Leaderboard screens.  Enough about the confusing gaming network – let’s just play already.

Gameplay
Fun.  Challenging.  Aesthetically pleasing.  These are a couple of things that come to mind when playing Feed Me Oil.  The music is soothing but still fits the description.  It is something I would picture would be playing if I happen to find myself in a scrap-yard where hills and machines are asking me to feed them oil.  I am not exactly sure what that means, but give the game a try and you may agree.

In fact, the music is reminiscent of Machinarium, another machine game world where oil flows freely.   In Feed Me Oil, your objective is to get the oil from a spout, into an area designated on the screen.  The elements range from blowers to magnets; windmills, wind spinners, gravity field changers, and more.  Put all of this together and you begin to have a highly challenging, fun, and time consuming game on your hands.  Of course the screens are setup similar to all other Chillingo games.  Level packs with multiple levels inside and a star rating to go along with each.

Solve the puzzle without all the provided elements, and you will receive more stars. Eventually you will need to dye the oil, sometimes through multiple dyers to make black oil turn yellow – then purple by heading through a blue dyer.  You can see even color mixing gets added into the challenge!

Hints
If you find yourself completely and utterly stuck on a level, you can start to use Tips.  These will show you, one by one, where to place the elements provided to you.  The catch is that you need to wait some time between tips in order to get the next one.  Impatient?  No problem, just throw down another $0.99 cents and unlock all tips without a wait between.  Even though I usually would recommend against this (I enjoy finishing games myself), Feed Me Oil can get so tricky – levels occasionally become almost impossible to beat without them.

Overall
Even after playing for a few hours, new elements were continuously added into the game as I progressed through more and more levels.  I’m only about half the way through, so I assume there are even more elements yet to be shown to me.  Even after you finish the entire game, you can redo the whole thing with reverse gravity.   This will cost you an additional $0.99 but is most likely worth it.  The cherry on top of this deal is that the app is free! (at least for now).  Get it while you can, buy the unlimited tips feature, and start figuring out these puzzles.  As far as games go – this is a clear 10/10.
