I’m on an iPhone X, latest iOS update.

Since the last Phone Destroyer update, I’ve had a few crashes involving Fireball - when I hover it over the enemy avatar and their minions for targeting, it immediately freezes the game. After a minute the app eventually crashes and my phone gets noticeably hot.

Also, a longer-term issue isn’t really a bug I guess, but on the iPhone X, you close / minimize apps by swiping up from the bottom of the screen. This happens to be where your cards are, so I frequently accidentally close the app while trying to play a card. Often when I open the app again, even after just a second or two, the game disconnects and I lose. One fix I’ve seen works really well and is used by games like Hearthstone: they require you to swipe up once to enable the functionality (the little grey bar turns white), and swipe up a second time to close.
