The art style is pretty nice for an indie and is quite inticing to try out.
Unfortunately, the storytelling and gameplay are on the stale side.
I didnt play that much of the game, around 3-4 hours, but after taking a pause I dont really want to get back into it.
Its few mechanics dont allow for much complex gameplay. You swim around looking for fishing spots, use appropriate gear to get appropriate fish, sell the fish, upgrade boat, repeat. Your boat, even with the possibility of expansion, cant carry too much, so there isnt that much inventory management, especially if you catch larger fish. And usually you can get around 1,5 hauls worth in a day. Yes, there are building materials, upgrades, some loot, but its the same gameplay wise and it gets monotonous.
The vague corruption/sanity mechanics are more of an irritation than a challenge. You are getting more paranoid at night in the dark and theres nothing you can do about it. Only thing it accomplishes is dragging out the game, really.
There is storytelling, however I dont know how the main story arc played out, but people mention its dissapointing. There are side stories in the form of notes, some NPCs asking for help, some interesting areas that offered some mysterious assignments for a reward, etc., but nothing that was really captivating. And with the monotonous gameplay everything slowly turns into a drag.
Maybe if you want simpler gameplay and to enjoy some neat visuals then you can get your moneys worth from this, but otherwise I think its a bit dull and very overrated.
