Sonic runners revival!
It's the full original Sonic Runners game that was discontinued by SEGA, but dedicated fans have reviewed it via reverse engineering the backend server responses and patching the app to point to their servers to keep the app running.
Even though it's "just" a mobile game, it's surprisingly high quality, has a full blown story mode and even the multiplayer features still work!
That's just the sauna beer of the rest of the world. :D
