I totally understand having bad experiences with this in the past! Just to clarify, this specific zip actually only contained the .apk file and nothing else. I am a gamer too and I know exactly the gallery issue you are talking about (usually happens with renpy games), which is why I make sure to keep my builds as clean as possible. But to save you an extra step and avoid any further confusion, I have replaced the file with a direct .apk version. Happy Squatting!
