I am a big Paradise Towers enjoyer, so the idea of Business and Economy being opposing factions trapped in a spaceport where nobody ever comes and goes does, obviously, appeal to me. This story also has a flavour of The Face of Evil, where the two factions share a common ancestor yet have evolved to grow wary of each other.

Often, this kind of story tries to be a commentary on class politics and falls a little flat, but I felt that the machinations of Elder Bones were quite effective on that front here. I also liked the imagery of the Doctor and Mel bringing the summer - light and dark can work really well on audio when they're done well, and here I thought they were.

Overall, I struggled to follow the plot in places, and I felt the Wailers were a little underwhelming and I was a little confused about the point of them, but the resolution of the episode is neat enough and it was a pretty enjoyable listen. I find Six and Mel to be a delightful pair on audio, and their communications via the medium of video game high scores here was hilarious.
