It is too bad about the last third on Xen. I would have appreciated a shorter but better game. I think this is a case of making it longer just to satisy the common consumer and also making it harder just because you are getting close to the end. 2D platformers are 2D because they work well in 2D. I think with a well-thought out first and second half you're bound to be let down at the end. By the way, I've done both choices, but for what? The game ends either way.
