Thanks a lot! 
The main goal of our game is to provide an easy to learn fun gameplay that can get everyone excited even after a few minutes in. The core game is losely based on survival, but we are much more leaning towards fun combat and exploration. The survival is there to fill in the gaps and to give the player stuff to do and work his way up to be that awesome pirate captain he wants to be and to commandeer that ultimate ship. We just posted an in-depth gameplay FAQ on our indieDB page, you should definitly check it out if you want to know a bit more about the gameplay.
