Okay I am giving a hint for people who are possibly stuck on the first thing, but this is the only hint you guys get!
Say "Help." on the first scene. After that you should be able to figure out the rest by asking Mango.
ALSO, if you are having SOUND ISSUES, try disabling / removing microphones you do NOT use, so that the game picks the correct one. I should've added a menu to pick them, but it slipped my mind...
MORE SOUND ISSUES - Discord can eat microphone input, so try to play this outside of a call if it doesn't work!
