A nice sequel. The combat portions were a bit awkward; generally interactivity is a plus, but I'm not sure whether the story benefited. Love the tie-in to the first game.
When I first got the wizard's "Enslave" spell, I saw it needed xp to recharge and I was like "Aww... it's like Heal; I can't just spam it." Sorta feeling down about it, since my fireballs one-shot most enemies anyway and my mirror spell made a more reliable minion anyway. Then I successfully enslaved a giant dragon. :)
Would be nice if fuel wasn't consumed, or at least not as quickly, when I'm not pressing forward or backward. Especially when boosts are more common than fuel on the second map... I'd like to just glide along on boost when possible xD
