a great game that takes an old concept and improves it. The different color of tiles and the hit chance on your own ships are a good idea, and the different types of ships and the upgrade system make it more interesting. its fun to collect ships, upgrade them and build up a fleet.
I already played some of NullGames creations and know that you reuse the same artworks for ships, but its okay because they look good. I hope this game makes it through the judgement. =)
