Flotsam

This is a very relaxed colony sim. If you have played oxygen not included, this would be right up your alley while being far less challenging.

Flotsam is a charming and relaxing city builder that can easily pull you in for hours. You start with a small floating settlement and gradually grow it into a thriving community, providing shelter, food, and jobs for your drifters. One of the things I enjoyed most is the scavenging aspect of the game. Nearly everything you encounter can become a valuable resource. From flooded ruins and abandoned cars sticking out of the water to remnants of old factories and even floating garbage drifting across the sea, there's always something worth collecting and recycling. Watching your settlement expand through ingenuity and resourcefulness feels very rewarding. As you progress, you'll unlock new technologies and innovations that improve the lives of your people and allow your floating city to become more efficient and self-sustaining. The game's atmosphere, art style, and overall pacing make it easy to lose track of time. I personally spent around 3.5 hours with Flotsam and had a great time. While I don't see myself continuing my playthrough, that comes down to my own preferences rather than any fault of the game itself. During my time with it, I found it enjoyable, well made, and easy to get immersed in. If you enjoy city builders, resource management, and the idea of building a community on a floating world made from salvaged materials, Flotsam is definitely worth checking out. Just be prepared to spend quite a few hours exploring, scavenging, and expanding your settlement.
