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
