Not much of an improvement
OK, there's a lot more to this game than there was to EW1, but more doesn't necessarily mean better, especially when the old problems are still there.
Main problem: it's way too easy until you get to the boss, when it becomes way too hard. I got through the entire game without even coming close to losing my castle, and then didn't even drain the frog boss of half his HP before being wiped out. And where's the fun in firing volley after volley of arrows at a boss with so many hit points? Where's the skill?
Solution to this is to test it more: adjust the difficulty so that you can't quite fend off the monsters with only your arrows and have to try balancing summoning creatures with upgrading your weapons. Basically, you need to test and tweak it a lot more.
The other problem is the story. Oh dear. Favourite "bad" bit: "we were like a snake without a head, fangs but no poison". Since when did a headless snake have fangs? That's just one example of many where the writing tries to sound impressive and just fails by making no sense. Cut it way WAY back - no more than a page per battle - and there's probably a good story in there somewhere without the laughable prose. And try to come up with some reason why YOU are so important within this story. Why are YOU the greatest general of them all?
