I've been really enjoying the game, but I've noticed a few things. There are some ships that are glitched and don't take damage as well as being able to go through them. That's not a big deal though. One big issue I found was that I think an island can become invisible and invulnerable to damage because I have been shot by multiple massive cannons from nowhere and instantly died with lower-level ships. Also, the islands can still shoot after being destroyed which can kill you after a well-fought battle :/ Besides those issues, I absolutely love the game. But I think the submarine should get a buff it's pretty useless at the moment.
