Hi Pompausiai. Initially, I wasn't sure how to enter the building and was running around with just a gas can. If the door was a little more obvious or similar that would be nice.
The boats went around both directions of the island, and initially I was reporting the top square because that is where I saw the boat, but I was supposed to report it's final direction instead. I had to restart the game multiple times because I didn't realize this. Somehow, I opened some radio frequency menu and I didn't know how to get out of it so I ended up just quitting the game at that point. I hope that helps understand what I experienced! You could work on a v2 of the game. :)
