You realize you guys don't necessarily have to wait until beta to release it, you guys can release it closed in alpha if you want, I promise I won't tell anyone what I see however I'm guessing that will actually be less convenient, either way just giving my 2 cents.

Also I checked out your music, I've always liked ambiance music for some reason, don't know why, but this is top quality work, congrats

Keep up the good work.
