I'm running on 15, what version are you running?
Might be my specific model.
Anyways, I like the basic premise of this game, had to emulate it to play it, while I am torn on AI art in general, I think your use of it is better than most. Since you're using your art as the base and it tries to fill it in. Though heavy reliance on it might sour the game later on down the line.
I have problems too but in two tablets with android 9 and 12 both with 2GB of RAM, in place of show some message it just close alone after few seconds of the start.
I have a 11 years old phone with 6" screen and 3GB of RAM but Android 7 it just say I can't install because version.
I didn't wanted install in my main phone since I already installed more than 300 apps and games in it already. XD
I am curious about what you meant by emulate.
Alot of peeps use emulators on pc to play and run android apps. As for the game not working on older phones that makes sense, android did away with 32bit support so older games wont work on newer phones and also inversely they don't really support 64 bit on newer applications being developed which means newer programs and apps pry wont work on older phones moving forward. So yee, @.@
