Its good. You can use multiple tilesets in one room, you have auto-overlap so there's no worrying about layers, rtp is way better than the last one and is pure eye-candy. Plus, it seems like (though the editable versions of this feature, like many others, are not implemented at the time of this release) you can manipulate battle backgrounds to sway and jiggle. Furthermore, framereate increased, fullscreen is much prettier and feels more like a videogame.
Other than that it is difficult to judge because at this point they havent implemented half of the features yet.
By the way, they've not yet updated any of the RTP sounds, and minimal RTP is included.
That help?
