Creator of subterbaldi (the mod), good to have an android port for the mod available since I probably won't have time to due to school
although the port does have some flaws like text and shaders stuff which I assume that you've decompiled the game on your own, If that's the case I just wanted to say that I already had the Open Source of Subterbaldi available for use, which if you sometime plan doing a update to the port.
