I'm really excited about the updated demo.
I tried downloading the zip version and playing it, but there's a pretty serious bug in battle- whenever a character tries to use Danmaku Shot, the game freezes up and gives a Loading Error: 'Failed To Load: img/animations/StateDown1.png'
This makes the first fight after Wriggle joins unbeatable, as far as I can tell. Even if you don't use Danmaku, the fairies will, and that causes the same error.
