About Project Castaway

✦ AI summary

Project Castaway is a survival crafting game where you hunt, gather, and build your way to safety across a sprawling Pacific archipelago filled with unique resources and environmental dangers. Master your sanity and the elements as you construct rafts and shelters, scavenge shipwrecks, and fend off the psychological toll of isolation and supernatural threats lurking in the night.

Project Castaway is survival crafting title set in the vast expanse of the Pacific Ocean. Hunt, gather, fell trees and embark on expeditions to traverse the ocean - discovering desert islands laden with unique resources. Embark on the life of a true castaway - stranded on a deserted island, with just yourself for company. Scavenge or hunt for food, traverse from island to island and be carefully construct rafts & shelters for when the night comes - it can get awfully cold on these islands...

Being stranded has some upsides, at least. Explore beautiful Pacific landscapes. Swim through shimmering blue water to stand upon golden sands as waves crash against your feet. When the weather turns, take cover under palm trees as the rain pelts the ocean - and listen to the thunder crash overhead. Use the natural materials surrounding you to construct a base - the key to your survival. Hunt animals, fell trees and scavenge ruined ships as you build your way to safety. You best keep your wits about you - it can get lonely on these islands, and castaways have been known to lose their minds... Keep on top of your sanity and ensure that you're sleeping well - lest unnatural apparitions appear before you, seeking to take your life.

✦ AI summary

Project Castaway is a survival game in early access that players find fundamentally unfinished, with numerous game-breaking bugs including broken eating mechanics, save corruption, item duplication, broken co-op functionality, and temperature management issues that severely hamper enjoyment. While the game shows some potential and initial hours might offer mild entertainment for grinding-focused players, the pervasive technical problems and lack of content make the experience frustrating and ultimately not worth purchasing in its current state.

The game is very basic and low quality, even for early access. It should have a demo available instead. Needs more development

it is not worth it because it has no story at all . you will feel good in starting but in middle all things get bored

Multiplayer still has issues with items appearing/disappearing on either player experience, but overall fun as long s you communicate.

game is not finshed and plenty of bugs

I really wanted to like this game, but there are simply too many broken things. While the initial couple hours might be reasonably fun if you like grinding, eventually the frustration will take over. Here's what broke me: 1. eating the most common food - coconuts - was broken for me. I press E, the little circle fills in, but then nothing happens. 2. broken saving - I saved on a bed on my raft. But when I loaded my save, I was teleported back to my cottage on a different island. No way to reach my raft, no way to teleport back. 3. Wilson clones - you find the ball, you pick it and then you have 2 copies. One that wasn't picked and your copy in your hands. You drop it and it repeats. 4. Temperature management - it's seriously broken. You constantly overheat, but there's no clothes to make. You swim in an ocean and your temperature drops by tenth degree every minute or so. Am I supposed to just stay in water? Except few isolated places, there's nothing to do in water. 5. Progression is pathetic - you start with the stone tools. They suck. That's fine. But after a while you eventually manage to make bronze tools. They break down only slightly slower than stone. It takes 8 or 9 …

This game has potential but it has so many bugs that makes the game actually unplayable. 1. There is a bug when playing co-op where you cannot see the animation of the other player cutting down trees or cooking or doing anything. You also cannot share cooked items with other players. 2. There is a bug when going to sleep, the time stops and does not pass like it's supposed to, however your hunger and thirst goes down as if you did sleep. 3. The animation for cutting trees could be better - it's nothing like sons of forest.
