Strange, during the build tests for android the dialogue box was at the bottom, and it was also semi-transparent, I'll try to figure out what's wrong.
I'll let you also see a screen just made of the same scene from the android phone version.
Maybe it was corrupted during install? I'm not a programmer so I'm not aware of the possibilities. Also, am I too gather that when the "signals" page says (not in game) that you are at the end of the build?
That's right, I prepare the signal in advance to let the players know what's coming next.
