As other mentioned, the video quality is really great. I did enjoyed the commentaries but you were hard to hear sometime, maybe lower the game audio a little bit. I think you are using audacity and used the noise removal, i can hear some artifacts in the game sound so what you can try to do is to record the microphone and game audio on separate tracks so that you can adjust them when processing the video in premiere/vegas or any other video processing software you might have.
you got great content on your channel, really love horror games !
