Nice game, graphics are consistent and cute, and the storm makes things more intense.
I'd give an option to switch to tank controls though, cause it threw me off when navigating quite often with the up/down/left/right scheme.
There's also hidden colliders which made it annoying to navigate, and taking damage for no reason was frustrating.
Not sure if its the storm "bumping" your ship, but it should be visualized with waves VFX, that visually moves toward your ship so you can avoid it with some skill.
I'd suggest making the cargo pickups automatic as the player gets close instead of having to keep pressing E.
A timer for the storm would also be good, and a compass showing the direction to the other harbor so players can focus on collecting the boxes.
Other than that, with some polish it could be a really nice game.
