TWEWY was a good game, so long as you don't mind rapidly aging your DS screen from the non-stop stylus swiping.
No, it wasn't and isn't a good game. It got praised to high heavens because of its unique style and music, but at the end of the day it doesn't have much substance to offer. It has no dungeons, so any gameplay activities come down to "fight a few battles in this area" to proceed. There aren't many locations either. It's a very small game that gets stretched by lots of story and meaningless collectibles.
