that's oki :3
we need to know what's ur phone model to address the situation. other people are not in fact having the same issues, u're the first person to report having a white screen in every scene in the game, and u're the first person to report having their save corrupted, which shouldn't even be possible? so i'd like to gather as much information as i can if that's ok with u
also, the "bluriness" can be adjusted in settings by changing the resolution, though it might get laggier depending on ur phone
