A different and very enjoyable take on idle/gardening games! In some ways the lack of a planting feature makes this more relaxing since you're just tending what the garden is coming up with, but being able to dig up plants and add water gives you a surprising amount of freedom. It feels more like a landscape-tending game than a typical gardening game, like you're caring for a patch of native plants in some desert/desertified landscape rather than a man-made yard, but in my opinion that makes it more interesting to play. The audio is soothing without becoming obtrusive and I love watching the different plants sprout and grow! Being unable to plant specific things also makes the combining-plant aspect a little more of a game; I could try cultivating an area until I get specific results, but so far I've been having fun just watching it go. As an idle game, though, it's something I've only been playing while I'm at my laptop; leaving it open and untended, as others have mentioned, results in a truly impressive (?) amount of dry grass.
Overall it's an interesting concept with a distinctive look, and I'm looking forward to more pseudo-gardening and more plants to observe!
