My first impression was "This person has played a short hike". The vibes, the visuals. Once I encountered the NPC dialogue it was sealed haha.
I wanted to experience this game more, but I kept encountering control issues and frustrations.
My first issue encountered is I didn't realize I could jump, and walked straight off the pier into the water instead of on the vessel. Took a while to figure out how to get back on.
Then I didn't understand how to interact with the facilities on the vessel. I had talked to the NPC that told me the controls, but when they told me to use the space bar to interact with things, I thought that it was going to be objects I found in the water or on other islands. It took me a few moments to understand you have to hold spacebar in conjunction with W/S to use the different facilities.
I almost wish there was a spacebar prompt + the W/S prompt.
Off I went sailing, until I realized I was going the wrong direction, as the compass wanted me to go around the starting island. That felt a little bad having to go the opposite way the vessel is originally pointing.
Then I felt like sailing was a bit slow, but I understood this was a 1:1 - which in concept is cool, and I often want to make realistic games, but I often find the realism diminishes the experience. It's not fun. But I also understand that this game might not be for me. I see people in the comments enjoying it and that's wonderful.
I then realized I could zoom out and that was exciting, it gave context for the scale, and how far I had traveled, that felt good, and made me feel better with how long sailing took.
While waiting on the vessel, I was contemplating how I didn't really understand how to control the vessel, despite reading the instructions from the NPC multiple times. I was pleased to find out that there is a bit of a 'ghost' version of the sails to show you where you should put it depending on the wind. That felt nice.
I then finally get to the first island. The vessel automatically puts it's anchor down, but I want to get a bit closer, so I lift the anchor and try to go forward, when I lift the anchor the vessel moves backwards. "Okay this must be as close as I can get" I think. So I jump off the vessel into the water. That's a mistake my character plummets to the bottom of the water, and I can't move or see where they are. I have to ALT+F4 out of the game. Feeling so bad that I have to restart the whole process. I reload the game and find myself pleased that the vessel had saved its location as the NPC mention, and that my character was now back on the vessel.
So I try to sail around a bit closer to land, this time I'm able to jump off onto land, wonderful! Except the vessel is continuing to move, and starts to clip into the land! OH NO!
I race onto the vessel as it descends into the earth, frantically trying to use it's controls. I try to anchor it to make it stop moving, but this would prove to be my final and fatal mistake. The vessel had now saved it's position in the earth, and anytime I reload the game I rediscover it's interned fate. 
I don't know how to reset the save / progress, I would love to explore this game more, exploration in games is one of my favourite design pillars.
As a closing note I will say, I love how this feels like such a personal game, the location, feel, and mechanics are so bespoke to what feels like the authors interests and I love that.
Wonderful job!
