Nice work! All these pieces feel like a part of a cohesive whole, nailing your hypothetical game. Favourite track was Cereberus Circuit.
I agree with Skremzy that the lead synth lines could be a bit more upfront, treated like a lead vocal would be. Possibly why Cereberus was my favourite, the lead melodies jumped out more in this tune, switching between rhythm section jams, then a melody popping out in the next. 

Awesome work, I hope you're proud of it :D 

Ok, this is my favorite of the whole jam

*** 
A race to die for - Ohh. a dash of mystery, rocking beats and effects... caves:?

Old Bones - Funky! (Damn, I love those “drill” sounds in my ears )

Ghoul Graveyard - BOO! Scary? Yes! That descending synthesizer is cool! Alien sounds, dynamic bass... what more do you need to be happy...?

Cerberus Circut - ...and for total happiness we need more gurgling sounds, organs..... guitars!? Sounds like Sonic Mania + boo!

The Final Drift - The dynamics are off the charts..... I'm feeling a little Prodigy.

Repentance Raceway - Need I say anything else? Well... I like the spacey arpeggio and the little break with the bass!

Hell Of A Tourney - Yay! Victory!!! Do they give me a lollipop?)

The only comment I can give in general is the ending of the tracks. I would very much like to hear other variations of the ending of the tracks, for slowly fading slowly gets tiresome (But this is more my personal quibble)

Huge amount of different sounds, experiments, motifs and one big dynamic! That's what I love the most!

Cool work! It's like listening to a full soundtrack for a game!

I listened to all the publications and left yours for last. What can I say? Yours is my favorite. It's the most dynamic, the most fun and the closest to my heart)

I hope your publication will be appreciated, because it is really cool! I hope you win :>

I really enjoyed this soundtrack and I loved that you brought Halloween into it hahaha, I would so play this game

This was a really fun soundtrack to listen to from start to finish. I love the racing theme you are going for combined with the breakcore sound. The synths you used were ear candy, and the melodies and riffs were quite catchy. I particularly enjoyed that silly sounding synth and walking bass line in the last track. 

If there were any changes/fixes I would suggest, I would of liked to hear the various synth melodies more clearly. I feel like sometimes during songs, they were meshed in with the other instrumentation and could of shone brighter in the mix. I would also ease up on the compression in more intense parts, but I understand that's generally part of breakcore music.

A cool collection of soundbites for sure!
