As for that, it's an audiobook of Aleph's Surprise Conflict.
I liked this! I wasn't sure about the robot voice at first (how it just drones out "maf" in a deadpan voice-- had to refer to the original text to figure out what in blazes it was saying), and the way it interprets laughter is hilarious, but it actually wasn't too bad once I got used to it. Quite enjoyed placing the background music too. Have you considered adding sound effects? Things like footsteps or battle sounds would add a lot, I think.
As for the story, I again admit to having not much idea what was going on since I haven't been following the rest of your stories. Until I showed up and started wreaking things, which I of course approve of. When the petrify orb scene came up, I thought, "oh, that's a good idea, I should--" and then it's literally me.
Liked the fight scene! Nicely over-the-top.
