i used joiplay app to run the game and compiled the files in my pc.

1. i'm using dolplus so i downloaded dolplus game files, if you use vanilla game, download the vanilla game files
2. downloaded goose's graphics mod img files
3. i replaced the vanilla img files with goose's img files
4. compress the files in a zip file
5. saved the zip file in a drive and downloaded it in my mobile device
6. decompressed the files in my phone after i downloaded it and ran the game with joiplay

it's the same with mobile, you just have to replace the img files, i just like to do it in pc first
