It would be easier to control, if the camera did not follow the character perfectly. If it waited until the character was towards the sides it would make circling enemies while attacking easier (the enemy wouldn't move x/y wise).
Its hard to see the difference in the ship types. And the pricing doesn't correlate to the statistics. A Galleon is much cheaper than a Fluyte, but has much better specs.
Great game, lots of strategy to how you outfit your guy. quick note: It took me a 10mins to realize the golden dots that shoot out of deads guys is money.
