From Hell's Heart is so awesome! Got all 13 journal pages, died probably 6 times, got terrified many a time from the sea monster. You can throw sea mines, harpoons, and a cannon. The tumultuous waves are huge, and affect the gameplay a lot which makes the whole ride perilous in addition to the sea monster. If you find oil, it ups the fuel counter which is pretty much the timer of the game. There are sedentary whales lying around that you can kill for sweet sweet oil and more goodies to keep on surviving. There is a frustration where sometimes you can't see the sea monster because he's way down below and he'll constantly chomp on your butt without your awareness, so there are some cheap deaths.
It's basically the Moby Dick game I've been waiting for.
