Very very very well done! The visuals are magnificent, also the UI and the animations!! The game idea is very solid and I could only see a bug: when you run out of money and you are sailing, you can buy infinite cookies. But it's good anyways, because the game is hard as it is! Maybe it needs some more balancing, to be able to earn some money or to get more biscuits.
I really hope you keep on with this project, because it's beautiful, fun, and if you could achieve this in such a short amount of time, you can do a very good indie game with some more time! Really. It has a lot of identity and potential.
Congratulations for all the hard work and for that optimal skills you have in your team!
