I literally just finished listening and already I forgot what this audio was about. It's just completely unmemorable.

I don't like Five much at the best of times, and while I like his characterisation best in the last few episodes, which do have Peri in them, none of that has translated to this story. Peri has never been one of my favourite companions, and the Ice Warriors are a reoccurring antagonist I find fairly dull. All this led to me having very low expectations, which were only slightly superseded by this story actually being mostly serviceable. While it's not very interesting and doesn't do anything new, it wasn't a complete snoozefest. Still, it's not a story I'm likely to revisit, just because there's nothing there.
