Pretty fun! It's funny how the music was so peaceful and serene while I was blasting away at innocent merchant ships. Having to maintain my ammo, food and repair my ship was cool, but would've liked some upgrades as well.
The game froze during the boss battle with the big ship that shot 3 cannoballs at once. I got it looking like just a big metal cannon, then shot at it for awhile, and then it froze - my guess this happened as the thing was about to explode.
