Ok, first of all- I'd really like to add my name to the leaderboard! I have the first place right now! I want those bragging rights :)
Over all- not bad. I like how the difficulty escalated, and how the container ships could move one another.
What I didn't like was that you could only move in four directions. I found myself pushing two buttons to diagonally all the time.
Also- any game that calls me 'laddie' gotta be good :)
