I'm helping my roommate write a game called "Green Mad Whale". I didn't have much time so I used an old idea I wrote a couple of years ago about a whale-catcher in Nantucket, trying to save his best friend; the green, mad whale. The game is supposed to be done in four weeks so there is not much time, but I'll do my best.
I got a lot of inspiration from the book "The heart of the sea" that is the true story behind the book "Moby Dick" by Herman Melville. The reality is even scarier han the original as there actually was a whale that attacked and sank the 238 ton whale-ship "Essex", outside the pacific in 1820. The men ended up in lifeboats and drifted for months at sea - surviving by starting to eat each other. One of the eyewitnesses to this remarkable event was the 14-year old captains boy Thomas Nickerson. His unedited manuscript wasn't found until 1960 on an attic and so much of the book is based on his words. Read it, you won't regret it.
