I think this game looks beautifal. Environment and "creatures" look creepy which is good. I think you should add some melee action with blocking. I would assume ammuntion on a ship would be limited. I would want a "creature" to limp after i shot it in leg since they're so damn resilent. Other than that, the game looks gorgeous! The ship would be so small how would you be able to make a game out of that? Unless you can go out into the icebergs or board a rescue ship or sumthing.
graphics: hot
gameplay: little stale (like being mauled by dude with axe though)
sound:good (could be better by adding weezeing breathing/people talkin to selves)
advantages/disadvantages: im not aware of any actually
