Some really interesting concepts here! The keys driving Onward are really nice, and the supporting instrumentation around does a great job of bolstering the main melodies. I like how the track devolves into a kind of military drone as it ends, capitalizing on the feeling of heading into battle.
Against All Odds is fantastic, and probably my favorite of the three. It reminds me of a bunch of different games from back in the retro days. The main section gives some loose Sonic the Hedgehog vibes at times, which is always fun. Choice of voicings here is really nice throughout; plenty of variety to make for quite the aural palette. The main melody is super catchy!
Wrapping things up with New Adventure - this very much divides the mix in two but it works well. Heavy, driven basses offset by the pleasant upper-range square-like melodies. Again, there are some great melodies here. This track seems to have more identifiable sections than the others. Big fan of how the piece quietens and slows down in the middle section and then slowly works its way back up to the energy at the beginning of the track.
All in all, a very fun listen. Great work!
