Brainbow!

Enter the seventh sky to meet, feed and fly wild unicorns, going on adventures through the clouds. Your unicorn can grow to activate portals to magical worlds where, for the count of 33, you can collect stars and eat fruits and vegetables that make you stronger, smarter, and wiser!
In this game you can make friends with other unicorns, bring life to the mountains, perform in synchronized aerial acrobatics, and navigate the shifting landscape as it goes from day to night and back.

This prototype is in development in Unity 3D, being tested on mobile and XReal AR glasses
