(Android) when i open it stays in a black screen for some seconds and just closes it, any ideas? (sorry for bad English)
Sorry, I don't know how this could be fixed for you.
it doesn't run on older 32bit phones, mine has the same problem, and it seems that it has already tried to optimize it as much as possible
It's a hardware issue, the dev would probably need to make a version for 32 bit phones as 1AA1 mentioned.
