Sigh... it must have been over a year since I've rated one of your pieces. Well, OpenLight, it's been a while. Just going to say a few things about this.
It's pretty amazing how fluent this is compared to things that you've done in the past. From the resonance of the piano to the minimalist drums, it all just seems less rigid and more like a steady stream. I also noticed that you included some tunes, styles, and rhythms from past works. (I was surprised to find some parts of my Passion remix buried within the beginning. Maybe you did that subconciously?)
You've become so much greater of a composer since 2010, when I was first viewing your music. An arguable thing is that the drum came in a bit suddenly in 1:10, but it's cool because a rhythm was already established. However, I'm not sure this would be very fitting of a game. I don't know much about Battleblock Theater, so maybe I'm wrong.
I think you overlooked this because, the more you listen to this, the less slow it feels, but for people listening so intently for the first time, it's a bit too slow for a game. That's the only reason you didn't get a 5-star rating.
I'm definitely going to download and loop this music. It really is exceptional; something that can easily be compared to the top weekly audio. I hope this review could do your piece justice.
