Our campaigns are closed, and with it, all pledge opportunities. We can not offer any more changes, upgrades or additions to pledges made earlier.
If you are on a Multiple languages KS or IGG pledge, you will simply have access to all languages in the app, and you can switch between these, so no need to add anything to it.
If you are a single language backer, you will be able to, when the app is released, switch your language every 5 months and also be able to keep what you have done so far in the previous language and review it indefinitely.
