I enjoyed the upgrade loop of improving speed and fov. Those 2 specifically made the boat navigation more and more fun with every upgrade. I got fairly far, as I built all the things on the right side of the dock menu, however, there were a couple parts of the dock that had a wood cost that I couldn't build on.
The boat felt nice to control, though in the later part of the game it didn't feel like there was much in the way of challenge - something to amp up the stakes as you improve your boat would add some nice flavor, but given the time you had to make the game, it was well done!
