Listened through once, MP3s played over my car's audio. My biggest gripe is that the cacophony of tones and alarms overpowers the voices pretty regularly. A bit of compression might have saved this for me, but it also seems odd from a cockpit-voice-recorder standpoint. It's like you've had it both ways: found footage and immersive audio.
Teague's performance rocked my world, further galvanizing my fandom. The Grim-Dreadnaught scene had me going misty, as well as Blue's big monologue. Banter and world building: all high marks; references and callbacks: ditto. One exception there: did "high-explosive solutions" get a rule of three? I only noticed it twice. Sobered by the Invid ref <hat tip>.
Tense scenes: I feel like the performances could have been more nuanced. Line readings are mostly good, but they show evidence of being, "readings," as opposed to delivery of memorized (or putatively extemporaneous) material. Again with the beeps and sweeps: there's a baseline of noises when the tension is off so I mostly tune them out to hear the words, so I didn't feel the pressure being applied by the sfx as acutely as you'd like.
