Mysterious interactions.
Help some eggs into an incubator. Water some travelling plants, before sending them on their way. Help some furniture survive a flood, and then hang out with some fish.
This game is described as surreal, and it definitely is, but not in the unsettling, slightly menacing way that a lot of surreal things seem to be. It was strange, but it wasn't scary, and I enjoyed it.
Took about an hour to finish.
This was an interesting game. I figured it wouldn't be action packed, so I approached it with the intent of getting into the role of the lone trawlerperson, and I found it meditative to sit in the boat's cabin, hearing the rain and the waves.
The downside here for me is that I love boats, and, wanting to get into the spirit of the thing, I set out to trawl, dropped the net and headed in a straight line for perhaps half an hour at a time, occasionally staring out over the waves or recording my thoughts on the typewriter in my cabin. Suffice it to say, and with no intent of spoiling anything, that's not how you play Trawl.
I think a writer would have fun with this game. I'm no writer, but this game gave me the experience of reading my real life book while sitting in my in game cabin, and I think that's a fun experience.
