Again, that doesn't help me at all. Where does it get black? Is it only showing black screen from the get go? is it during fights? Level transitions? Which levels? Have you tried another device? Have you tried redownloading and reinstalling the game?
Because I've played the whole game twice now (pretty fun) and I haven't encountered any black screens. Though I searched a bit and some people mention they experience that with the android build, but again, not much info on where it happens
