I updated the demo that's available. It doesn't have any new content, but it does have better, non-RTP battle music. It also fixes the three elements I renamed, though there are probably still some places where they're listed as they were.
Some more significant changes include that the mass level up system now works all the time rather than just at the end of a day or night. That means you can switch your party members on the fly without fear of them being too low level to do any good. It's also a little easier to level up now. Less grinding is always a good thing, right?
