Hi, this is most likely because your device is 32-bit, while the app is 64-bit.
In the next updates, I'll try to compile it so that it works on 32-bit phones as well, but I don't like the stability of the game when supporting 32 bits, and in general, 32-bit apps are becoming a thing of the past, and I have no idea if the game will run stably on your 32-bit device.
