Black Riddles Studio, the developers behind Crazy Justice, have revealed that save data on the same account can be shared on all platforms.
That includes Nintendo Switch, PS4, and PC, the platforms which Crazy Justice are launching on.
Do you mean cross-save? ? If so, then yes! You can access the same account and saved datas on all platforms (include PS4) ?
