This is a very eclectic soundtrack, I think there's like 10 genres in this, if the game really existed I'm sure it would be a fun and a weird one.
The immediate switch to second track startled me, they sound completely different. "Funky Flies" is a nice small beat.
I like the chord progression on "Welcome To Your Inner City" and I'm %100 sure that this is a reference to Toby Fox's City theme on Deltarune Chapter 2 (forgot the song name), the progression sounds even alike (the watery jingles sounded a bit out of place though).
The mixing could be better by changing the volume on some instruments (especially the 5th and 7th track, they sound very loud), the orchestral instruments mixed with chiptune felt sometimes a bit out of place, otherwise nice work!
