You guys have good back and forth at times. At the beginning, it seemed a little like whoever was playing was having issues keeping up with banter because of how hard the game is.
The live view seemed to block some of the action at times. I would move it into one of the bottom corners and buy a cheap $10 green screen to put behind you and edit it out of the video so you see just the both of you and block less of the action.
To be honest, i didn't like a lot of the editing where you cover up the action in the game. The 420 doritos thing was a little funny, but when you do that it takes the game out of the lets play.
This will sound harsh and I'm sorry, but the no-uh part was by far the worst 5 seconds of the video. If a joke falls flat in a video, you still have the gameplay for people to enjoy, but for 5 seconds the only thing you gave to the viewers in video and commentary was "ha ha we mispronounced a word". And that's a shame because it looks like you made custom art for all the no-uhs and put most of the editting effort into that.
My point is you can edit stuff into your gameplay vids, but dont edit completely over it. Your commentary and editing effects need to compliment the gameplay, which should be the focus most of the time.
Your gameplay,audio, and video was good though.
