The graphics looked nice and the presentation was very cinematic. The sound effects and music conveyed the underwater feeling very well.
The invisible walls underwater were pretty jarring though. locking the player to a fixed path in such an open environment felt strange and made it more confusing than it should have since I didn’t know what areas were blocked off. It took me a while to realize I could swim over the boat to the last shrimp. I assumed there would be an invisible wall there too and ignored that path a few times.
I liked the dark twist the game took at the end
