Nice game! I managed to get 314 before succumbing. I'm mad that when brainstorming ideas for the theme, pirates didn't even cross my mind! I'm a fool! As for gameplay, I basically agree with what CFHM said about the upgrades. Even with the legend in the description it was hard to make them out and the text was small and disappeared quickly. The controls were snappy, and arcadey in a good way. Overall it's a good submission!
