I think I will go with the first font, but I am also tempted by the last one, any input is welcome.
I have decided that I do not want narration in my animation, so the text will be very important. I have been looking at title sequences and the dynamic uses of text that many of them display. I don't think that I want my titles to passively appear and disappear, having them interact with the world they described, even in a small way, could make it more memorable. I am considering have the title for each phase behave in a different way, so that they are distinguished even further. I could perhaps have them behave in a way that has something to do with what happens in the phase they describe.
Here are a few titles that I have found the most influential.
