Thanks for the reply ! We were pressed for time and the game is really unfinished ^^"
This is the first time I've used Unity (and proBuilder) for level design, I originally come from Unreal Engine.
The dialogue system was implemented at the very end, my team members didn't have much free time to work on the jam , so we did what we could. :)
In fact, the captain is mainly there to bring the game to an end. The "maintenance" he's talking about is more to signify that the game isn't finished x)
I take note of the feedback, thank you again for paying attention to our almost-game ! :D
