hey! ❤️❤️❤️
this sounds like chrome's standard crash screen instead of something going wrong with the game ^^; the most likely scenario is that the game takes up more resources than your device can handle while running.
if you're able to, i would recommend you download the game! that will help it run much smoother :)
aside from that, i don't think there's much else i can do. i'm so sorry!
