Pretty cool concept! I think the enemy aggro range needs a little tuning since it's way too low, and you can just destroy each ship without them even starting to move. I'd also suggest adjusting the audio, it's currently a little too loud and doesn't loop. Still a solid entry!

Nice Game! The Enemy Ai though seems to be a bit Buggy. After I shot 1 Enemy, all other Enemies stopped moving and stand still. Sometimes Enemies who were still moving appeared but its more of a Rarity. The Game did Lag in the Browser Version but downloading did indeed seem to fix that Problem. 

Lagged a bit in the windows version as well, and the sail blocking your view in camera mode made it hard to shoot forward. Sailing around shooting cannons is always a good time! The boat bouncing against the water goes a long way in selling the movement.

I really like the idea of having more than one AI. Imagine if I could have four AIs assigned to all Gen3 members and have a battle royale in the ocean of mine.  Haha

There's definitely a lot of room for improvement here, but it's a good start.
