I made this game using Unity for some friends in my homeschool group.
I eventually released it on the Play Store but took it down after a year or so. You could play Flappy Bird as members of the group and it was just meant as a fun game for them.
You can download the APK file for the app here.
The original caption was "This is a fun little game I made for my local homeschool group. You play as 16 of the people as they navigate through series of random pipes."
