Can I just say how happy I am to see Panel de Pon finally get some love? : D
A font size between the two would work the best, I think.
At the moment those are the two options. Both are included as image fonts. We can edit them, but haven't been able to resize yet. And yea. I've been trying to grow the Panel De Pon community a bit. Most of our translation work is taking place over at reddit.com/r/paneldepon.
About PdP, are the texts moving/animated? I seem to notice that the text are like jumping?
Nope. That's just how it looks. Interestingly, the Japanese doesn't do this, but when we switch to english they look like that. There is an option for animated text, but not like what you are thinking (It's more like each letter bounces, similar to the main menu).
