The new game from Bart Bonte is sharp yellow and black. The first-signal system activates! Wasps! Hornets! Caution Bio-Hazard! Caution Wet Floor! Slow Down! The last one is correct, no need to hurry anywhere, we've got awesome relaxing game with 25 levels (PC) or 50 levels (Android/iOS), with beautiful graphics, vivid music and great puzzles. Well, you may played the game already as Bart Bonte on his blog says that it passed one million downloads on Google Play recently...
The goal of each level is make your screen yellow without a trace of black. Use your mouse or finger to move with objects. Some puzzles require tilting of your device and that's probably why PC version is shorter.
So, in case you are not one from the million of happy players, there is an awesome game waiting for you! And in case you played the game earlier, why not replay it? Have a good time and enjoy!
Also, a big congratulations to Bart Bonte on his success!

I'm not fast enough to do 14
If you're talking about 14 on PC, the one with
two yellow circles and black background stripes
the trick is that
the bottom button lights up for the same duration that you held down the top button
so just
hold the top button for about 15 seconds, which is way more than enough time for you to click all the stripes.
Level 21
Most of the youtube walkthroughs have 3 circles for level 21, but I finally found one with 4 circles at
https://www.youtube.com/watch?v=cKQvC3-NmIQ
The game's hint says to turn the one pointing down to the right, counterclockwise, a quarter turn.
Now turn the one at the bottom right clockwise a quarter turn.
Now it should be easy to finish it, assuming you played/struggled with it long enough to see how to control 3 circles at a time.
Turn the one at the top left a half turn.
@barbara: In fact, all four hints (keep clicking the hint button) combine into a four-step solution to 21, which simplifies to the three-step one you gave.
Thanks kktkkr. I noticed that there was more than one hint when I got to level 22.
Note to self: Read hints carefully. The clue about more than one hint was right there at the beginning of the hint: "Hint 1".
I'm bad, i'm stuck at level 13 xD
