A unique set up with some design flaws.
The game definitely caught my eye just because it was a "boat" horror. Few game developers can make it believable to have such a unique atmosphere, the one like your game provides, although it does fail with the execution.
I enjoyed the atmosphere, the sound design, but, once again, the set up and mechanics seemed a bit odd, uncomfortable. I do realize this was made for a jam, which is the reason why that major complaint will be left as a suggestion note. Maybe with the improvement of the mechanics, the game can be easier and more enjoyable to play.
Wish you good luck with the future projects. Cheers!
Edit: I do wish to see an update to this game, would be splendid.
