OIL ACHIEVEMENTS (4 for 20
The following 4 achievements are obtained by using and manipulating the oil.
Feeding Hand - 5
Feed 5000ml of oil.
This will be obtained with natural completion of the game. Should be one of the first achievements you get. Just "feed" oil into the compartments to complete levels.
Oil Painter - 5
Paint 5000ml of oil.
This will also be obtained with natural progression. Later on in the game, you will be required to paint the oil different colors before sending it on its way to the compartments to complete each level. You do not need to actually complete the level, you can just paint the oil then reset the level.
Oil Spiller - 5
Lose 10000ml of oil.
This will also be obtained with natural progression. To "lose" oil, it must fall or slide off screen. This should be obtained early on in the game.
NOTE: This achievement was glitched at launch, but has since been patched. If you already played the game and did not delete your save, just boot up the game and the achievement should unlock at the main menu.
Oil Spill God - 5
Lose 50000ml of oil.
Same as "Oil Spiller," just lose more oil. This should come with natural progression. I got this in World 4. Luckily this one is not glitched.
MISCELLANEOUS ACHIEVEMENTS (7 for 60
The following 7 achievements are obtained by performing certain tasks which you may or may not complete with natural completion.
Keen Feeder - 10
Complete a level with +4 unused elements.
See "Feed Genius."
Feed Genius - 10
Complete a level with +5 unused elements.
These achievements simply require that you complete a level with at 4 and 5 unused elements. They are stackable, so completing a level with 5 elements unused will unlock both. If you are using a guide, you will definitely get this about half way through the game. If you are having trouble, check try Level 3-8, which is completed with 6 unused elements (see THIS VIDEO).
Buttons Cheater - 5
Complete a level with a button without oiling it.
Not a hard achievement, but it does require some thought. If you can't get this yourself, try Level 1-15 using only a fan.
Free Range Brain - 5
Do not use hints in 15 levels.
See "Organic Brain."
Organic Brain - 10
Do not use hints in 30 levels.
These require that you complete the stated number of levels without using any hints. Hints are given when you push the question mark near the top left of the screen. They generally tell you which elements you use and where to put them. If you are using a guide this is a freebie. If you are not using a guide, just replay the first level 30 times without using a hint. Thanks to J Lo for this method.
Thoughtful Feeder - 5
Think for 5 minutes in one level.
Just spend 5 minutes trying to solve one level in one sitting. This should come with natural progression, even if you are using as guide, as some of the levels require very precise placement of elements. Alternatively, if you are too smart, you could just leave your phone idle while in a level.
Keep Trying - 5
Set the oil flowing ten times in one level.
This should come with natural progression. Just start the oil flowing ten times without completing the level. This can be quickly obtained by repeatedly tapping the faucet.
