Title: I actually heard this song last, and it feels like a nice summary of the other themes ;)
New New York: Your 'synthwave' is quite nice. I loved the resolution at 0:35, and the other chord changes at 0:42 and 0:45! It feels really soothing and calming, yet futuristic and sharp. And when you were dangling on the edge of being a bit repetitive with the synths, you cut it off temporarily at 2:50, which I think was a smart move (I just wish there were a few more).
Our Origin Story Begins: Feels perfectly like a 'start-battle': the beat is there, but calm enough not to give me 'FINAL BATTLE' vibes. The brass also adds this 'epicness' to it, I like it.
Worst Marksmen: Already feels a bit heavier than the previous song. You always know the right time to add variation, which prevents you from overusing one particular theme. Another nice one.
Fast Mart: Simple and cozy, fitting a shop. Here I would feel like I could relax a bit, yet still feel the pressure of the city in danger. Soft~
System42: Ooooh, me likey this! A simple beat, a nice instrument, sounds great!
Office Space: Nice introduction of a sneaking theme, yet still feeling this synthwave theme. Soft, with lots of silences, and with a nice melody. I like the bongo-drums and the 'water-drop-ticking' (I don't know my instruments). Really well done!
Impending Doom: Starting to simple, and immediately building up into a great battle theme. Nicely done! The drop at 2:35 was very nice, coming from a moment of calm-down. My favorite part was still 0:00 - 0:20, it was very nice.
Credits: Surprisingly, although I am sure you use major chords, it does not sound too major at the start. Something about those synths sound intrinsically minor to me or something xD. The trumpets do sound congratulatory.
But God, what many and long songs... took me a while to get through this one! Very nice though, well done :D
