At the start I wasn't really sure what am I supposed to be doing or looking for there... It's also a bit of a hassle of needing to hear the captain's dialogues every week because there wasn't any captions. It took me A WHILE, to see the "TARGET" and "CURRENT" words for the turning the radio signals, as well as that this is a "week and tasks" thing. But everything after that is quite understandable. And I think more of the talking was in your description rather than the game itself. It would be really helpful to have the explained mechanics stored somewhere as well, rather than keeping all in the audio message.
But that aside, really excellent artwork, the vibes are really sucked me in! The minigames were really fun too, they give the sense of completing a task under pressure. Lastly, I got the neutral ending, haha.
12 people is such an impressive number of people in a group to manage :0. Nice job!
