I enjoyed your overall sound; the chiptunes and strings blend very nicely together. The title theme is powerful and really stands out for me as the strongest track here. The offbeat snare drives the melancholic chords extremely well and the simple rhythmic synth that stays consistent for the whole song plays its role perfectly. This is also probably the "safest" track, as the rest of the album has some moments that are definitely pushing the envelope in terms of overall song form and structure. I love hearing those risks, and I feel like some of them work well and some of them don't quite land. Some of the latter could be my personal preference, but I'll give you the play by play for how my ears perceived it:
In "Glee," for example, the main lead feels like it could have benefited from "less is more." The lead plays such a long string of notes that it feels like it has lost some impact by the time we get to the end. The opening organ sounds are a strong intro, and the strings that come in as the song picks up pair well with the synth lead. The strings are playing such short notes here that I would have given them a bit less attack to make them play more of each note - as it is, the faster bits feel a bit unnatural. The synth is very punchy, which works great on its own, but it makes the shorter notes of the strings feel like they are lagging behind a little bit.
For "Grief," the intro is well done, especially the panned plucking sounds and the little bits of dissonance that come in before the song picks up. I like the chaotic synth that's introduced around 0:39, and the rhythm here is pretty non-standard which helps to drive the intended message of the song well. It contrasts nicely to the intro and the abrupt ending with just that little bit of echo leftover is a strong finish.
I enjoyed how you switched up the instruments in "Loneliness," the strings are very pretty and, together with the choir, create quite the melancholic feel. The sudden shift into acoustic guitar for the outro was unexpected and does a great job delivering the intended emotion of the song. This was definitely my favorite track.
"Love" has some very lovely sounding chords. It almost felt like a musical without the lyrics, in the overall structure of it. The climax of the song is properly cheesy in that regard, in a good kind of way that matches the tone of the song. There are a few notes in this song as well where the strings could have done with a bit less attack, IMO.
--------
The same melody being used in every song comes across nicely. Instrumentation works pretty well with each other for the most part, with my only real complaint being that the attack is a touch slow on the strings in those two songs. I would have loved to have seen some more musical tension to help drive home your intended emotions, especially in "Grief" and "Loneliness." While "Grief" was a cool track, "Floating Through Life" and evoked more emotion through my ears. Overall, solid work!
