Very Good! I was listening to a lot of your songs on spotify, however I just discovered that you post on Newgrounds as well.. here's a review
I'm pretty sure there's a chord progression, or maybe just chords; either way I love it, especially the sound design. I think the sound design perfectly fits the track, and is done in a way to make all the components blend into each other
The main melody(s) are made really well too, I love how they are quite steady and have a good structure, also I enjoy the melody itself too. Again, the sound design is amazing. What VST did you use? The choice of bells and the reese/saw at the end (3:04) is quite nice.
Drums are too good. The snare/rim is fits in really naturally; I like how it chances with the arrangement. The closed hat/shaker is, again, like the snare, very fitting and changes with the arrangement also. It's nice how the kick (or is it maybe an 808?) doesn't stand out too much from the bass, making it sound really nice and soft. The percussion in the background reminds me of Obsidian Moon and 繁殖期.
The bass blends in nice with the kick, and I feel like it's layered with one of the synths. Sound design is great, I like how it's more smooth than coarse.
Arrangement is S tier, one of the best parts of the song. It works very nicely with that one synth and the drums. I also really like the automation and effects, for example the bass fx at 1:59 and the distortion(?) at the end (3:38). The fade in at the beginning is also done well. Love how it transitions into just one synth (00:30) as a sort of "false start" instead of dropping immediately. Makes the drop hit SO much harder.
10/10 if I've ever heard one
