All right i'll go song by song and to the best I can as a constructive review (Permission to go hard on feedback was accepted by composer btw)
1. Main Theme - Good composition at 0:12 first time we hear the leitmotif its sounding great, although feels a little off rhythmically, some quantize will help. Second part of the theme played by the piano is nice but with all the instrumentation the piano range is around the same as some of the strings, that makes it a bit hard to try and figure out what's being played, then at 0:50 you come back in strenght and I would've change the strings a bit and made them move a little bit and change range to let some place to breath because you have a really nice woodwinds swells and we can barely hear them. at 1 min the bass and the chords stays too long on the same patern, mixing it up for the end climax would make everything better imo.
2. Breakfast - I like that you use the main theme back again but with a different arrangement, but you're staying on the same chords and pentatonic scale all the way, you can probably either transpose for a moment comme back or do a classic go to the fourth chord and come back just to change, even if the song is one minute.
3. Distractions, this one caught me off guard with the "boing" sound, I chuckled a little bit you got me, love it. Also the pizz can be toned down juste a little bit and you can probably at the end double it with a cello pizz just to add a little "oomph"
4. Shattered - Watch out for your piano velocity note I feel like if it hits too hard its getting almost distorted. Also this piece feels like it can be something else, I like the composition the idea, the build up attempt but its like you can add an entire orchestra around it. But I think you wanted to go piano only, in that case I would look more on how you can play different the piano and add some counter parts on the left hand, doesn't have to be too much.
5. Trials - Ok now we're getting in the cool part, the mood is amazing, the composition is really nice, the brass needs to be much much more in your face, double the cello spicatto with a double bass doing the same would make it sound wider more big. I get the leimotiv is back again nice job, the high strings too can probably be more in your face, a little less reverb or room verb they are too far away, you can probably automate it to gratually make them sound louder too will help the build up.
6. Death - Extremely simple, I think it works the only thing to think about is, after you die do you go back immeditally to gameplay or do you have a Continue ? Button if you have a continue button this could be an intro and then you'll have to put something to let the player not sit in silence. If that is not the case then It does the job, its very simple.
7. Strings voicing is honnestly kinda hard to do, I think it works but some voicing can switch place it stays too much in the center, you can probably drop 2 some violins and make the cello a little lower at some place and make it louder. at 1:00 I was expecting a sus4 to major chord but I guess not you got me. At 1:13 is a good exemple of using bass, its been a while since we are listening in high mid range a change of tone would help the listener imo. at 1:47 near the end you are doing the same chords on half-note until we reach the end I would keep the top note the same but move the middle notes of your strings just to change it up a tiny bit and not stay in the same monotone range.
8. The best one - Overcome - Leitmotif is back again on the cello, pretty subtle though, watch out for some chords the cello and high strings are clashing a little bit. at 0:55 seconds you are staying on the same note for a long time I was expecting a change but maybe thats the way you wanted it it still works I was juste feeling some change was needed there. The choir is a nice touch, but you can even go harder, add like a short low timapni roll to add some bass percussion and some staccato cello/double bass line doesn't have to be complicated. Because I don,t feel like the climax was amazing, it was good enough but it can bang so hard.
All right I hope that helps :) Good job !
