Calico is a day-in-the-life community sim game where you are given an important and adorable task: rebuild the town’s cat café and fill it with cute and cuddly creatures! Build up your café by filling it with cute furniture, fun decorations, yummy pastries, and get it bustling with animals again!

Calico is meant to make you feel all warm and fuzzy inside. The gameplay reflects that with a laid back, low stress creative environment to explore and play in.
