The game is fun. There's a strong Subnautica feel. You're dumped on a planet, there are lots of resources to collect, building is simple but enjoyable, lots of exploring, and you upgrade your equipment. I played just before the last patch (May 2021). There was about 20 hours worth of content. The game was clearly not finished at the time. The tech did not exist or was not functional to finish the terraforming. I wish there was a larger map and more places to explore. I believe those items were expanded in the most recent patch, so devs are on the right track. I still wish it would be a bigger world to explore though. The game also doesn't trigger the same fear responses I felt in Subnautica, because you're not underwater and there are no hostile enemies. I don't find myself wanting to replay the game the same way I do with Subnautica. Maybe if the devs add a touch more story and a way to finish the game I would be more interested. There's a generous demo (at least on steam? Not sure here) that you should try if you have any interest in the game.
