I like it, but because there's no place to grind, if you make bad purchases or miss fights for exp, you can get stuck. I don't want to have to restart the whole game or play with one eye on the wiki the whole time.
It's probably possible to get stuck, but you might also be surprised what's possible. If you're not having fun with a fight, I'd suggest asking on the forum and people might be able to help you through it. I do try to test all fights with a minimum level party to keep balance within a certain band.
