The constant white screen flashing effects needs to have a toggle. It hurts my eyes and head horribly and I have never been sensitive to visuals on any other game. My other complaint is many of the in game purchases do not have a way to view details about what the pack contains. You also should be able to toggle battle speed to at least 2 times speed increase. Overall the game is fun but the flashing not able to be disabled is game ruining for me. Which is a shame because I spend a lot of money
