Hi , eveyone i bought a APP on Microsoft Store, i have a PC, APPs can work on tablets or others gadgets, my APP after startup gets a black screen, but sound is OK, so i dont know if its just for tablets. I have searched here on GOG trying to find the same game, my question is.......is this game just for tablets or is there a pc version?

note: i have XBOX APPs...something, dont know what......emulator perhaps.....

If it is the same game sold on Google Play and the Apple store, then yes, it is a tablet/phone game only. I don't think I've ever seen a PC version of the game.

EDIT - This is the game, correct?
