I'm hoping for your sake that these just are not playing right because most of the time I can't understand what I'm hearing.
A large part of this is probably your instrumentation. Did you mean to have so many parts set to Orchestral Hit and Tubular Bells? Because if not, that's what it's set to for me. If you did mean to do that, I'd recommend changing some parts to other instruments to make everything clearer. For example, on Sin's Chance I only hear drums, bass, and two Chimes parts. The one carrying the melody is fine, I guess, but the bottom chimes part I would recommend changing to something else.
The only one I could really make anything out on was Sin's Chance and I wasn't that impressed. Well, I take that back - it depends really on how long you've been composing. It's very dissonant and that could be turned around to your advantage if you work on it some more.
Not trying to be mean or anything here, I'm always glad to have another composer around the forums. And from what I can tell as far as video game music goes, there is some potential here but these need some overhauling done to them.
What program do you use, by the way?
