-The dialogue box overlaps the selection box if the text is too long, and it barely uses half the width of the box before wrapping.
-The turret doesn't take the dead zone into account when deciding which direction to traverse in, so it gets stuck if you aim to the other side too quickly or switch to the other side around the back.
-I didn't have any trouble hitting enemies, but an indicator showing the turret's target rotation would still be nice.
-The railgun and torpedoes feel underwhelming.
-One of the gray enemies at the start of level 2 remains stationary and doesn't respond to being attacked.
-Game crashed on level 2 shortly after I killed a supply boat. Don't know if that was the cause. Didn't happen again.
-The delay before the supply boats drop their item is pretty annoying.
-Enemies have too much health.
-Enemy shots are too easy to avoid if you have enough space to not get surrounded, and the gray and yellow boats are too samey (if there's any difference at all). Maybe give the yellow ones a triple shot or make them lead their shots.
