I'm currently playing KBAP as well, and I'll quietly update the original review with a few observations, if I may.
1: Very 'chibi' - like dragon. Cute as a button. And quite powerful, yes; the rage system is an interesting mechanic.
3: Yees... well, that's not that new, in KBL you had a wife. Now you are a girl who can have one of several guys as .. 'companion'. Not sure if that's a big difference, except you don't get to make babies as far as I know.
4: The accomplishments thing is a nice touch, and makes sense in-game as well.
5: Kind of agree - I didn't have to ask anywhere, there's a small steering wheel on the minimap that activates 'navigation', it's real easy and works great, but you need to actually spot the darnthing. (Or read the manual). Still, that form of travelling is a HUGE improvement on the original.
And for the new points:
The new story is a ltitle more serious. Some of the humor of the original is missing, which is a bit of a downer for me - even if the humor was rather weird, it was fun. It has, possibly, shifted from a RPG spoof focus to a girl-as-hero thing, without making too much of a deal out of it.
A lot of things from KBL is reused - much of the units and even music is the same. The maps, areas, buildings, etc. are entirely new though; there is enough new but I wouldn't mind seeing a few more changes.
On the local 1c KBAP forum, I posted a link to the official game info thread - if you jump in blind you are likely to hit a brick wall after a while, and that will make it annoying, so I do recomment you check the island toughness order, or you might well jump to a deathtrap. The difficulty is a bit messy; I found normal quite hard, but easy WAAAAY too easy.
Rerading this it seems a bit negative... I'm not. It's a game I like a lot. I do believe that if you like this kind of game you'll love it.
