On the one hand, this is a pretty standard “tropey fantasy video game/novel from the perspective of the characters,” as seen in Dark Lord of Derkholm, A Practical Guide to Evil, and others. The addition of the Beta tester player, OTOH, is a delightful twist, as his deliberate attempts to break the programming make for some outrageously absurd situations.
The performance is done quite well, as expected with these performers, though there were a few isolated instances of lines being attributed to the wrong characters, and some readers will find the occasional background sound effects distracting.
Overall, I’m very much looking forward to the next book in the series.
