Neet sound design on the first track. It describe the AI parasite perfectly !
I really liked it's creepy melody too, perfect ambiance :)
I also liked the melody of your 2nd traces a lot, very light hearted.
The build in the middle of this 3rd track is really cool too.
Insane 4th track for a boss battle honestly! =0
There's a very consistent vibe overall the whole ost, great job!
