This was a cute little game. The mini-game was simple enough to figure out intuitively, and quick enough to not get quickly tiring from doing it a bunch. The flavor text and humor were good.
The first thing that stood out, escape is used to exit fullscreen, so it should not be your only button for backing out of things or getting into a menu for web games. We like to play jams games in fullscreen as a group, and this required using escape enough that it was a bit annoying. The cell phone menu is a cool idea, and it does look like your classic bar phone, but the contrast is a bit low, and it can be hard to read. I'd recommend adding a setting to change the default, or adding a button, to give it a backlight effect for higher contrast. The ship assembly area is near to the start and I got their early, but pressing the button it told me to use did nothing. There should really be a message of some sort about not having anything and nothing to do. The signs next to it are hard to read, especially at the default size. In the shop I could browse, and it showed the cost in red for what I could not afford and green for what I could, but trying to purchase the green items resulted in a shake effect on the item and I was not able to purchase anything. If the shop is not implemented, then it would be nice to have a message about that, even if just on the game page.
I collected some fish, and ship parts. Added a ship part to the build area, and looked around a bit. It seems like a neat little game and a decent start.
