That was amazing my friend! It was difficult but not impossible! Stylish and on point, I could tell what I had to do in the game instantly when I opened it without looking at the tutorial at all (which I also did later and yeah it was a good explanation hehe). There is not much I can point out, because honestly I think you nailed it, but there is one thing I can tell you didn't forgive in this game...MY KIND! THAT'S RIGHT! THE NON-ORGANISED PEOPLE! (Am joking by the way haha)
As I was playing the game, around the third level, I noticed how fast I had to move to pick up the calls, so I decided instead to pick each speaker in a line from left to right and keep alternating to be fast enough to completed it but...the top image happened haha. which is where the only add on I had in mind was..maybe when you right click the "connectors" they would instantly go back to their base to make the player's life a bit easier haha.
Overall man, that was amazing, It'll be surprised if you don't do well in this jam ay!
