The roles in Pulsar explained:

Pilot: shout at the engineer to give you more power, get shouted by the weapons officer for a firing solution, practice your "ooops" every time you crash into stuff, die suddently because the entire ship is on fire and you were focusing on the external camera

Scientist: you never have enough power for anything because everyone thinks you're useless, except when the ship is swarmed by viruses and/or they need urgent healing. It's like IT, you are only ever acknowledged when something goes wrong

Weapons officer: cackle maniacally and shout at the pilot and constantly annoy the captain for permission to launch the nuke. Spend all the crew money and scrap on gun upgrades because "the dps was higher"

Engineer: everyone constantly shouts at you for more power. But you know, you know the reactor is literally on the brink of meltdown. Even a single extra watt and you're all toast. You're always on fire. Everything is always on fire. Oh gods why is everything, even when everyone thinks nothing's wrong, always constantly on the brink of destruction? Nobody will ever understand just how close the ship is to exploding, all the time

Captain: somehow you need to be able to shout more loudly than a herd of cats on crack, but it doesn't matter because they don't follow you anyway. Except when you put a cap on pocket money, then the weapons officer will constantly ask for juuuust a bit more.
