Ah, I actually got it to work! I copied and replaced the included replace script over another version of the replace script that I already had, and it worked. I guess the my old one was just corrupt >_> (I got it from this site...)
This is a really fun script, and really hard! I had to tone down most of the spellcards before I could appreciate them, but they really are a blast. The spells nicely reflect the characters, too. There were some cool references in there. (: There's probably also a little too much random spam for most people. I didn't mind it at all, especially since it was so pretty with the star bullets.
Overall it was well balanced, anyways. (Except for the difficulty, oh god the difficulty. :p )
