Black Screen

[Veskooo98]

I am with Samsung Galaxy S3 Mini and stock rom is 4.1.2, but i am rooted and now i am with 5.1.1 (Yay game requires 5.0+ )

But i open the game test version (0.1) and i am with black screen lol

I see the logo picture then intro video (everything is ok) but later then video ends and load main menu RIP black scren with sound. i am happybecause others have the same problem , but i do not like Google Play store. Can i purchase app from other place than ******* google play because there says no devices supported because i am rooted 5.1c but store know my s3 mini with stock jellybean rom and i cant play it if purchase it. ******* work. I am fan and i just own PC game + both 2 dlcs and soundtrack and together and now problems. Can i enable ot install not compatible apps from playstore or get apk and purchase it from official site for example.

And is there any way to test it before purchase it. 

Thanks for help in advance.
