Nice tactics game! I'm guessing you are basing it off of "Into the Breach"? It seems a little easy. Maybe you need to add in something similar to the buildings in that game so you cant just dodge all the attacks.

It was planned to implement something similar as to have a better difficulty, however then it would've mostly just been a pirate clone of that game. I'm trying to come up with another mechanic to help set the difficulty though, with an idea being destructible collectibles being placed around the ship, which you'll only collect if you protect them throughout their entire battle
