This was a really good episode! I always enjoy streams and Let's Plays much more when there is more than one narrator present, as the interaction often makes them especially interesting (and funny). Hopefully, your brother is going to appear in other episodes in the future again.
At the beginning, I found it a little difficult to distinguish between your voices, as they do sound pretty similar. But there were also two actual audio problems: A few times, your voices became a bit too quiet or unclear to properly understand, and near the end the video and your commentary became increasingly desynched.
By the way, do you still have those old battlers ArtBane drew for the early version somewhere?
