0.3 was great, the game feels like it's got the right ratio of gameplay/pictures/text, and the writing avoids becoming too elaborate or showy. A favorite part of mine, spoiler-ish as it is, was the winged fellow later in the game. Grove's title change in the menu after the cutscene was a detail that I really liked.
One suggestion, though I'm not sure if RPGmaker permits, is to have a button for skipping cutscenes and reloading directly. Sometimes an enemy literally kicks your ass into submission repeatedly and getting out of it takes a while.
