Thanks for the feedback.
I have a couple ideas in mind to make the game more interesting since that's been a frequent criticism; just so I have a bit more information to work with did you find it boring due to the number of ships (ie, there were too few and it was too easy), or due to the gameplay itself (ie, the mechanics as they stand weren't particularly interesting)?
I'm also a bit confused about the theme issue. You play it by spinning the lighthouse's light. I'll try to think of ways to make that clearer though.
