I have the fastest ship in the navy, not only moves faster but it dies faster as well :D So I tried on a more of a defensive build and didn't really work... then I went balanced, and our ship "Raid Flyes and Mosquitoes" made it to the Danger Zone with overconfidence, that was our pride and our doom...
The game is cool, would totally work for a mobile/tablet game since doesn't require much attention and can be played just with happy little taping. Graphics were fun, I've seen the HELP signal while playing, as well as the flags, love little details like those!
The only thing I would suggest is to make it easier since doesn't absolutely depend on how well you are playing the battles. Also, it would be nice to repair the ship whit the money you've got, even if you can't afford all of it. Love it!
