I figured out a way to play gaia fishing in full screen mode

[sweetune]

well... rather than full screen, it's more big screen mode.

If you use google chrome/firefox then there is the zoom button. (or ctrl+ / ctrl- )
I think it's nice to play in a bigger window than the tiny one we have originally. =)

if you zoom in, it's still smooth movement and clear images. =)

sadly, it doesn't work with jigsaw =(
