Crack Pairing: The Author herself likes to make these in sketches on her tumblr account, amongst them there were Abel/Phobos, Abel/Deimos, Deimos/Phobos, Keeler/Cain and so on. Fans have since show interest in crack pairings themselves.
Unintentionally Unsympathetic: Praxis. He's out to prove that Cain is no good but his methods are shoddy and his unrequited crush on Abel makes his motives questionable as well as obsessive. His poor new navigator, Ethos, often has his attempts to be closer shot down due to Praxis being more interested in Abel. They're starting to get along better but it takes Abel to tell him to pay attention to him.
The Woobie: Ethos, Praxis' new navigator. All he wants is to be closer to his fighter but Praxis is too obsessed with making sure Cain's true colors are revealed and possibly trying to steal Abel away for himself. For all it's worth, he actually doesn't show any visible resentment toward Abel about the situation.
Deimos can be pretty sympathetic too. His navigator is an asshole and possibly borderline abusive and his feelings for Cain are unrequited.
Repairing your craft supposedly cost 2000 sovereigns, and in fact if your bank balance was below 2000 sovereigns you couldn't get repairs. However, if your bank balance was above 2000 sovereigns, you'd get repaired but the 2000 sovereigns wouldn't actually be deducted from your account. Which meant that repairs were free.
Your Beam Weapon did damage in inverse proportion to your distance to the target. At range 0, its damage was infinite.
Speeds were supposed to be limited to multiples of 2 — 0, 1, 2, 4, 8, 16, 32, 64, and 128, depending on which key (0-7) you pressed. However, you could hold down 2 number keys at the same time, and their speeds would be added together; holding down all keys from 0 through 7 at the same time would theoretically give you a maximum speed of 255.
However, if you were playing on a TRS-80 Model 1, this presented another problem: Holding down more than 2 keys at the same time could result in the cheap keyboard hardware thinking you'd pressed a third key unrelated to the other two. Pressing too many velocity keys at once could throw you into Navigation mode, fire your weapon, cause you to turn, etc..
