Also, I forgot to mention,
The sound design is so brutal and satisfying lol. That music though, my gawd. Did you make that music or did you get it from elsewhere ?
I made all sounds and music. I do sound editing in Audacity, just picking up random fx from the internet, mix them, change pitch, reverberation, and so on, so that sounds will fit actions in the game. I make soundtracks by using DJEN (random generator of guitar riffs), I just set instruments, some combination of notes, and then generate a couple of hundreds of fragments, choose the best ones, and make a whole track out of them in Audacity.
