Great game, this must have been a lot of work! I like how simple the concept is, yet there is a lot to it. The in-game tutorial messages worked pretty well. The controls feel good and firing the harpoon to grab things is a fun mechanic. The graphics and music nicely set the atmosphere.
The Hitbox on the bigger versions of the ship seemed smaller than I expected, but I guess that is on purpose?
Overall great concept and great execution!
