Hello, I am Tom from Bulgaria - web developer, gamer and game translator. I would like to work on official translation of your game into Bulgarian for free.
I have my own group of translators so we can translate it - http://steamcommunity.com/groups/BulgarianTranslators. We have worked on Serious Sam 3, Toki Tori 2+, CSPromod and more.
Feel free to add me on Steam - http://steamcommunity.com/id/WildBeastBG.
Thanks for your time!
