Giygas appeared!
The start made me think of Giygas with just that low echo hum sound I was hearing there. Then I started to hear some other heavy sounds and kept thinking of Giygas anyways. Very dark feeling song though. The vocals were cool and then it switched to what feels like a really fast and pumped up feeling boss battle style song in my opinion.
The dark hum near the start gives a feel of Giygas being before you at the Infinite Devil Machine and you have to hurry before it consumes all time periods and makes everything totally chaotic forever. The louder strange sound sounded a bit like someone moving plastic wrap around a lot and adding some effects to it to make it creepy.
I like how there is a bit of glitchstepping added to this song for that perfect feel of things starting to go wrong in the battle as you await its next move while you have Paula keep praying and hoping for it to be defeated.
The drums here were really smooth and I like how it feels a lot like triplet notes there coming on and off very quickly. The synth seems to have a heavy amount of distortion added to give that feel of it fading and coming back incredibly fast. The bass here was great and very deep as well.
Overall, amazingly great song. Would love to hear it in some kind of dark boss battle too. Great work here.
