Woah, that's some really awesome synth work you've got going on there. :D

The low rumble of the synths in the buildups are really effective at conveying startling fear and the feeling of "I need to escape!". IMO you took the buildup-drop concept and used it in such a way that it actually enhances the vibe you are trying to convey. I can see this in a video game where you escape lava erupting from a volcano; halfway through, you think you're safe, but then the earth starts to rumble more, and the lava starts catching up with you. Then, at the end, you're safe from harm, sweating and thinking "That was a close one."

Awesome job, no notes. :)
