Feels like a constant downfall listening to this, as if something is just going deeper and deeper. You did a very good job at making the song feel countdown-y and as if you're running out of time! While the chords repeat, you managed to make it vary throughout the whole piece making it not sound boring and in fact pretty suspenseful. Instrumentation choice is perfect, and the bass and plucks you chose really help. Great work, keep it up!
