Atom Pals
Atom Pals is a cozy virtual pet game that runs in your browser. You hatch a little pet, name it, and raise it. Feed it, pet it, play catch with it, and find the one spot it likes being tickled. It grows up through four stages, and when it's ready it curls into a cocoon and hatches into its next form right in front of you. You can race it on land, in the water and in the sky, play a couple of mini-games for coins, and spend them in the shop on food, toys and outfits. Every pet has its own colour and personality. The garden keeps going while you're away, so when you come back your pet has been off doing its own thing. There's a cozy mode where nothing bad can happen, and a devoted mode with real stakes if you want them.
