I have completed the game, and it definitely has the vibe of Exalted Modern (without Exalted mechanics, of course). Spirit grants power, you now have the power to unleash Awesome ™, and the fight scenes are properly Exalted.
One thing, though: It’s unclear what stat fighting uses. Is it the stat of your weapon, or of your Spirit?
And I definitely hope that Jamie’s life or death carries forward important consequences through the story. It’s an origin-defining event, after all.
