Topic, Level "Rhythm & Blues", game "Path 4 Mouse"

  @Ferrari: I agree so, and it happens in some of my previous puzzles, too. :\

  There was a slight flaw in the thumbnail which has now been corrected!

  Burfy: I will be sending you a message right away!

Sherlock: It took my quite a while to figure out a system which would, to the greatest possible extent, prevent random actions from resulting in completion of the level. Puzzle-level-makers in general tend to care too little for this in my opinion :/

  I think I noticed everything, but it does not help :)

  @burfy: Have you noticed something? :) Not only on the gaming screen.

Edit:
@Ferrari: And also I was shaked by your controlling of the procedure. Tried another several possible methods after I got the puzzle, but it really doesn't work. :) So strict.

  Yes Ferrari I will appreciate it... I still cannot find the logic even though I know how to do it.

  Great! Congratulations :)

  Got the puzzle. :-)

  As you have already completed the level, would you like me to clarify my reasoning in a PM?

  Hmmm, I have no idea why... the thumbnail confuses me...
