Great concept, good execution. but here's my criticism (if you want it)...
Some of the writing is forced. Seems like the actors keep repeating back the information so the audience knows what was said on the other line. I think you can get away with it a few times here and there, but when it's every single line it starts to feel very fake. There needs to be some lines that are more vague. It's ok to make your audience think a little bit and figure out what they're talking about without hearing both sides of it.
