— Thank you! I've already tried that as I wrote in my first comment. The game run well on my phone's browser, but not when installed as an apk.
By the way, I have just made some tests on other devices. Here is the result:
Device | Play on browser | Play as apk app
ASUS Zenfone 2 | Fine | Bad
Samsung Galaxy S7 Edge | Fine | Fine
Samsung Galaxy Tab 4 | Fine | Fine
Samsung Galaxy S4 | Fine | Fine
It seems that most of Samsung devices can run the game well as apk. I'm not sure with other labels due to lacking of devices of them.
