We've uploaded a guide for creating translation packs that will be compatible with ToA for anyone who wants to create their own translations. The game now supports arbitrary character sets, asset replacement, and full text replacement, including a system for fully grammatical translations with dynamic text.
We may at some point distribute official translation packs as well.
If you're working on a translation, feel free to shout it out here. If you've got any questions about translations, including requests, feel free to ask here as well!
