Very nice game! I feel like you really nailed the ship to ship combat - the steering felt right the cannon felt powerful. Also the progression was fun. I'm not sure the potions were really needed though - seem like it's better to just upgrade the ship. I also felt like it was too zoomed in - I constantly needed to click on the spyglass
The pixel art was really good - but it was a little funny that the island is so beautiful, and the sea were you do the actual combat is just plan texture with some ships on it, which is what you look at for most of the game
I had a weird bug were after defeting the summoning boss - I went to the shipyard and maxed out the upgrades, but it's seem like ships were shooting me while it happens (heards cannons and saw my hp drop), and than I got the game over screen lol. Pirates never play fair I guess :)
