“I don't think this game deserves the bad reviews I've had a lot of fun with it so far. Scuffed for sure but this is honestly one of the better island survival game I've played (there's like 3 or 4 basically).”

“It's been almost a year since I first tried the game, and I got back to it just now, after the full release. On the positive side, the game looks fine, I was glad to see several new options for building, although I…”
“If I hear just one more tape with my uncle saying "he is sorry" and telling me to be careful, I will lose it. Seriously. Dude is very, very repetitive. I mean, I get it, uncle was nuts and blablabla. But can't I simply…”
“Hello! Overall I like the game. I like the graphics, the colors, the ambient movement and the ocean. Even the music although I always play the music low to be aware of the ambient sound. At this point I'm pretty much…”

“Awesome dev team – it really helped that we could play together seamlessly. The gameplay is great, and if you enjoy survival games, this is definitely one to try. It’s both challenging and a lot of fun!”
“understanding of the game takes a bit but you fit into it you start to injoy it more and more, but i do wish the game was more crispt”
“It a great survival experience. Based on Stranded deep (which I love) but more complex, islands are more intricate, survival is more difficult, Aggressive animals have a very good AI. When you are attacked by a snake…”

“The game is improving and getting better each update 👍 Keep it going. Now with coop mode it makes real fun. But exchanging items must be fixed, if I drop items the other players can not see them”

“The game is really good and isn't getting the recollection it deserves. Its a more modern and visually beautiful stranded deep. It plays nice, similar to green hell and SD combined. Its a great game and worth the money.…”

“Game is a mix of Stranded Deep and Green hell, and i hoped it would be best of both world (ambience of SD, and survival mechanic of GH). But in the end it quite the opposite. World just feels empty, animals have totally…”
“Finished the game after 22 hour grinding hours. This game is by far not finished. It is very unpolished. The UI is not great, inventory management is a pain, building and moving mechanics are not consistent. Many…”
“Do not waste your money on this game. It launched into early access a year ago and straight away negative discussions were getting blocked. The game has barely changed. The new content that was added during early access…”

“Overpriced scavenger hunt. Most of the time you can’t complete because the one part was magically flung into the woods or deep water. Buy Stranded Deep. It’s a much better game.”

“Not gonna lie, I was invested... 43 hours in just to realize that the "Quests" don't Activate in Coop. No Bottle Notes, No Sticky Notes, No Quest Completion. Kind of Annoying. The game is fun, I mean I made it 40+ hours Scavenging, Building, Exploring before I even realized…”
— a player, Steam review · 40 hrs played“I truly don't understand where all the hate for this game comes from. It's a bare bones survival game. This is EXACTLY how it would be if you were stranded on an island irl. Of course gathering resources will be repetitive. Of course you'll have to sleep and do things to…”
— a player, Steam review · 71 hrs played“This game could be so good! The 3 hours i spent playing co-op in the 1.0 release was much more enjoyable than all the time spent in the game solo so far (about 16 hrs because solo is a slog). Co-op being shoehorned in will most likely be its downfall. Not because of the co-op…”
