The game was pretty easy to pick up with a bit of playing, though could still benefit from a bit more details on what things are used for/do. Is there a benefit from more crew? Can you get anything other than gold from exploring islands? What does the spyglass do?
When I first started I was surrounded and destroyed pretty quickly. The second try I ran as soon as I started and slowly figured things out. That playthrough I quickly was able to upgrade the ship to max and felt like I ran out of things to do. The islands just gave gold, which seems to only be used to buy temporary upgrades such as a shield, which I didn't need, and a spyglass, that I'm not sure what it does. There looked to be status/informational indicators that I had these and time remaining for them on the left side, but it was flickering and showed faintly making it hard to read. I sailed around for a bit trying things out and getting a score over 1300, before getting bored of simply wiping out everything I came across without a challenge. The game could use with a better difficulty progression. The start should give you at least a little time to get your bearings before sending in enemies. Late game needs more to do to challenge the player.
The game was also fairly laggy. It was playable, but could use optimizing, as the regular lagging was annoying.
