It's just some PDFs guys, and they work fine for me.
I like it. It's certainly far better than the last fillable PDF character sheet I saw. Nice work!
I don't like the Landscape format, and I am used to having combat stuff on the left and skills on the right. But those are things I could get used to.
I found when trying to enter a power that the "Attack" drop-down doesn't include many things, like Intelligence or Strength.
So what is the difference between the two files?
