Not all of them! I just choose to show you the ones that I think are most important. The first difference is that in this version of Azur Lane, there is no Level Up System. This means that you won't be able to increase your level in this version of Azur Lane. The second difference is that there are no In-App Purchases (IAP). This means that you won't be able to purchase new characters or items in this version of Azur Lane. The third difference is no ads! This means that you won't be seeing ads while playing this version of Azur Lane!
