Great use of layering. World of Memory is a fantastic example of gradual progression and I love the warbly synths that kick in around the half-way point. The stripped, unplugged vibe that comes with Colorsplash Beach is a nice change of dynamics and tonality from the swell of emotion that came with the track prior, and it is offset just enough by the lead synth to tie it together.
My favorite of the bunch is Fight to Remember - it reminds me of something I'd hear in a PSX-era RPG, but also something a little more modern. Kicking in during the dialog that precedes a fight and then fully transitioning into the busy sections when the battle has begun. Great choice of not only the instrumentation but gradual progression with this one. The piano and strings at 1:44 in particular give me some serious Breath of the Wild kind of feelings. Great work!
