Preserve from developer Bitmap Galaxy is a nature-building puzzle game where you build tiles in an interesting mix of horizontal and vertical gameplay that's just left Early Access. It's really sweet, great to unwind with.
Here you just keep on adding layers of nature until it all fits nicely together. The idea is that you're restoring and building up various diverse connected biomes and it really does look lovely while you're playing it. A soft casual puzzle game that won't make your brain sweat, accessible thanks to the clean and clear design and engaging enough to keep you going as you want to see what happens as you place all the tiles down to watch it come alive. Dorfromantik was one of their main inspirations for it, so if you've seen or played that, you know some of what to expect.
During Early Access it managed to get a Very Positive rating from Steam players. It launches with Native Linux support and Valve rated it Steam Deck Playable (some small text / on-screen keyboard has to be pulled up manually).
