I don't beleive there has yet been a Moby Dick- The Video Game walkthrough, so here goes.
Firstly, you start off as a small whale, barely able to lift yourself out of the water, and most fish can outswim you. Teach them a lesson. Eat a few fish, then go for the single pirates on the small boats. Bat these around with your fin you you head until either the ship breaks or the man falls out. Be careful of two man ships, as one of them is usually an archer, and arrows damage your health.
When you reach a suitable size, you should start heading for either two man or three man boats, but evade nets, arrows and harpoons, as these will either damage you (arrows, harpoon), or slow you down (net). An easy way to destroy small two man ships is to either click (boost) when you are near the surface to smack the boat from the bottom, and then sink it in when you land on it, or tip one of the men out. Be warned, doing this earns less points.
Avoid pirate ships or big galleons, as these fire masses or harpoons, nets, arrows, and, uniquely cannonballs. These knock large chunks of your health off, and unless you are quite big and have alot of health, these can be your undoing.
If you want to get large combo of either fish or sailors (eating alot in a short space of time of the same thing make a combo), destroy alot of ships but leave the sailors floating, the whipe round and skin the surface of the water eating those on the surface, then whip down to eat those that are sinking. For fish, wait til there are large amounts of octopus, then sweeps the bottom floor and press boost, which will chomp up fish as well.
When you are large (between 50 or 100 tons), start attacking galleons. This game is almost physics orientated, repeatedly hitting the galleon with small weak attacks will barely hurt it, while you will be an easy target for nets and cannonballs. First, boost into the bottm of it, prefferably towards the sides of the galleon. This will knock a few sailors off, and (with the size you should be at) launch you into the air. Make sure to land either you or your tail onto the boat, and this will damage it alot. Repeatedly swim to the bottom and swim back upwards, knocking the boats bottom, and you should destroy it in no time.
These are just basic principles, and aren't very specialised to getting certain in game achievements or combos. If you want that please comment and I will do the best I can. Or comment on my page and I will do more. I hope you find this helpful, as this is a great new game and I enjoyed playing and completing it.
This isn't a bad walkthrough, but I think many people are fine with randomly thrashing about and destroying everything while being killed lots of times...
It's a well constructed walkthrough, but it makes the game seem more complicated than it actually is. If you couldn't work out everything in this walkthrough by just playing the game, you're an idiot.
Well it was a little hard getting the 20 Fish Combo when the whale was small, so I waited until it was large enough and used boost while swimming on the bottom of the ocean to catch as many fish as I could.
