Hockey Slam is a hockey shootout game on Android which I built almost from scratch. Some of the engine features include 3D graphics with PBR materials, a rudimentary physics system, replays, a multithreaded job system and a hot-reload DLL platform for developing on Windows.
I detailed the creation of the game in it's own post, but now that time has passed I am releasing the source code and assets under the MIT license. You can still find the making of here: https://hockeyslam.com/makingof
I'm happy to answer any questions you might have.
