Nvidia Shield games on non-nvidia devices

Recently I've downloaded nvidia game on my Sony Xperia z5. The game started, on my suprise, and I couldn't play because I didn't have joystick connected so I took another phone and using app called BT controller I was able to play. But then I've downloaded half-life, and it also booted but after credits it shut down, don't know what was the problem but other games worked, I was even able to stream game to my TV via chromecast.
If you have any knowledge on this, could you help me please. Thanks!
