@AlexisXelasix@Atlus_West You won't be able to play it. Offline versions of gachas are still rare and you'd need to wait for like 5 more years until it has enough content to justify turning it into a "full" experience (if it doesn't shutdown before that).
@LuminariaParty I'm looking for anyone who still has Luminaria on their (Android) phone, so I guess it will be the right place to look at? (If there are any people). I want to remake the game (as far as my skills will allow) in future and I'm missing some of the game's files.
