This was super ambitious, very nice work! Some things I liked:
The subtle animation boil on the player's ship was cute
Voice acting
Lots of different missions to complete
Crossing stuff off the list was fun
I did find the red/green buoys to be a bit annoying to have to deal with, and I didn't understand quite where their areas of effect were at first. Also going into debt before you really know what you're doing was also frustrating, I would suggest giving the player some time to get the hang of the gameplay loop before implementing some of the penalties like red zones and the debt collection.
Overall very nice work!
