hey:) we have this gif: 
oh and here is a higher quality version of it https://streamable.com/oxe56b - 
you need to choose the booth first, then the sector (500-D) (number on top - letters below the "STR" title) and then the Building nr which in this case is 11. You also need to time it to be connected before 19 and ensure it is stable until 20 in this case - green wire means the call started. I know this is a lot xD. We'll add a better tutorial after the jam rating period ends:D. Thanks a lot for the good vibes!
I did it! I got successfully culled lol (I hope I was suppose to get that ending). And now that I figured the mechanics out, it got me more curious about the story... I hope your team work more on it! I did still got yellow lines occasionally, meaning the call was interjected. Does that mean I got the wrong number or booth?
