i'm not the dev, but t's absolutely normal, especially for big games. big games can't store the entire game in just the APK, so you're pretty much downloading the APK and the game files (including its audio, photos, videos, etc.) separately and then it has to ask for permission to access those files to run it
Hi, thank you for your reply mate. Did a bit of digging and you are completely right.
For android 10 and lower, big games only asks for READ_EXTERNAL_STORAGE permission. But with newer android versions, that single permission is split into the ones I saw. Thanks again for clearing things up mate, really appreciate it.
PS: I really really love your harem visual novel Love by the Water, it has such lively characters and great overall vibe. Didnt know I would find you here lol
