I had a lot of fun with this game, but I do agree that it gets somewhat repetitive after some time. I like the overall game mechanics, but I believe it would be much more interesting with more strategy elements such as:
- Different types of ships (in the game, you have two main strategy possibilities, one is having bigger and meaner boats and the other is having trade ships to make more money and use expensive ammunition). Maybe a class system could be added, where you would have a more varied range of ships, for example tanks (more hp), support (heals other ships), offensive (deal more damage), saboteur (stuns enemies), etc. This way players would be more entertained choosing better approaches to defeat an enemy, which would also have varied squads and strategies.
-More combat maneuvers (I really couldn`t understand how sail and crew shots worked), such as defend (one ship takes damage for another), stun, taunt (cause enemies to focus on a ship), repair, etc.
-An aiming system, where the player could choose between a conventional attack or to shoot at a vulnerable point in the enemies ship, but with a chance of missing
Some other things that could be improved/added:
-Harder boss fight (waaay too easy)
-Different turn-based system, where instead of moving all of your ships on your turn, each ship would have an individual time to recover AP (based on a "speed" attribute)
-A cool customization and item system, where the player could equip their ships with different types of weapons, sails and hulls with different characteristics.
Despite the deficit in terms of strategy, the game is fun and quite addictive. I hope to see a sequel with some of theses features!
