Hi, I just stumbled on this topic and found about this game. Being a Queen fan myself I gave it a try and had no problem installing it and playing the demo.
I’m running FOOS 21.03.0-rel.2 since android 9 update a few days ago. I don’t know if it is needed for this game but I also have flashed opengapps arm-9.0-pico following this guide.
Once again I have no clue if it is related but I installed it from aurora store with anonymous account. I have no idea how to buy the full game in these conditions but the demo works great though.
I have OpenGL ES 3.0 enabled. I also enabled hardware-accelerated video playback after installation and the game is still running great.
Hope it can help, and thanks for making me discover this game.
