Hello, Will here (one of the UBE organisers).
1. You are free to do as you wish and creative solutions are encouraged, so no restrictions as far as we are concerned. We're interested in the process of (ideally, creative, inclusive and accessible, but that's up to you) localization, so also encourage participants to explain any choices they made. The slides shared with the lockit were designed to facilitate this but you are free to do so in other ways.
2. We didn't develop the game so don't know for sure, though it's a certainly a reasonable guess. Again, all creative solutions, and transcreations, are welcome.
