I may have hit the same bug as everyone else. I can't seem to make any money, and therefore progress any further. The tutorial is long but worth going through, as I was enjoying the game until I got stuck. The music is very chill too.
Since it seems you'll be fixing / adding to this after the jam, could you add a colour-blind mode to help with two brown-ish corals?
I think you've got real potential for a full game here, well done. :)
