This is such a charming simple little game. It's a waiting game, but a game of this type that you just buy, and have, and there's no microtransactions maybe contributes to how peaceful and simple and charming it is. It's essentially a little garden that you tend, and check back in on periodically. You can grow plants, and sell them to buy fertiizer and seeds and other such simple additions, or improve your shop to get more customers.
But the cornerstone of this game is the cross-breeding. You can cross-pollinate plants with each other to make new species, and those species are created according to specific rules. The game within a game is figuring out what those rules are, so you can eventually create any plant you want. You end up really feeling in control of your virtual garden. It's a beautiful game and I love it to bits.
