Such a cute little take on the same idea!
I had a lot of fun with your voices, and also the meta-fun by giving me the ability to uniquely connect “random-but-fated” people together!
I was however hoping to be able to use the other two pretty (teased) cables, and would have liked to be able to do the connecting myself (tried to click and drag a bit and felt silly when I realised…), but I get why those were left out. I also found it odd that the Operator physically disconnects, but is still able to hear the callers talk?
All in all though, I think you made a very cutesy, atmospheric little game, and I love to see it!
