Great orchestration ! Very spooky vibe.
I don't know if it's the sounds you've used (or the way you've composed), but it really feels like a video game. And it's cool.
If I may be so critical, in the last 40 seconds, the melody is too redundant for my taste. I'd have liked a little more variation.
Yet the arrangement varies a lot and brilliantly.
Tell me what you think, it's only a personal opinion.
