We had a lot of interest in a Spanish Translation as well, and today I'm pleased to announce it is done! You can select it in the options menu once you've downloaded the update.
The translator also said it was tough to distinguish the lower case u from v in the default font (and I've had complaints about the font before), so I edited it to be crisper and have a larger difference between the two - and this will affect all languages that use the default font!
Aground is also 66% for the Steam Autumn Sale - so if you haven't gotten Aground yet, or hesitated because it wasn't available in Spanish, now's your chance!
