I played through Trawl a couple times. It's got great atmosphere. The gameplay is lacking inasmuch as, best I can tell, everything you pull up is pretty random and I'd like to see a bit of story added to the objects. But, as an idea that presumably is the inspiration for another game, it's still pretty cool. I guess I should probably check to see fi the dev has expanded upon this IP.

I really like how the radio locates the objects but breaks after three uses, giving you a vignette of sorts. And, so far, I haven't had repeat items. 

Also, the sounds of the boat, and especially when you are moving levers or turning the wheel, is pretty cool, and I also thought the way the radio frequently sort of escalates until you get the bell ring was also neat.

This feel more like a proof of concept, but I think it's successful in what it sets out to do.
