How does your game fit the theme?
Player is supposed to fish in the ocean to sell them in order to clear his debt taken by the curel lord. Ocean's weather is too uncertain and a storm can hit at any time. The player must prepare his vessel with enough resources to hold it in the storm. While the player is fishing, there will be minigame where they will shoot the spear, or lay the fishing net etc. The fish will be of different kind and have different effects on the tool being used to hunt them.
At-least this was the idea. I could only made fraction of that minigame.

Did you write all the code and made all the assets from scratch?
Yes.
