Montessori Nature

Montessori Nature is a garden building and management game. It is meant to teach kids the basics of gardening, seasons and weather. It is free of any in-app purchase and wait time. It is made in Unity 3D and has community garden mode where you can collaborate online to create a garden. I was responsible for the whole development of the game.

Try it, it's available on Google Play and on the Apple App Store.
