Welcome Back Home: This is a beautiful melody. I’m a sucker for piano tracks like this that convey a lot of emotion. To me the melody sounds like it has the structure of a Beatles song, but with a more cinematic accompaniment which makes for a really nice combination!
It’s Engie, not Angie: I really like the old clockwork sound effects - they give this shop theme so much character. The contrast of the fast percussion with the slow waltz piano creates a feeling of calm energy, or maybe this is a representation of being in the zone or in the flow state when you are super focused while working on something you enjoy. In any case, it makes it fun to listen to!
Lamppost: The harmonic progression you use in this track is really interesting, still light-hearted, but slightly warmer/more subdued which nicely accompanies an evening stroll sound. Love the metric modulation to the ¾ time signature - that was a very smooth transition!
Great Hospitality/Blackout: The glockenspiel part, particularly with the delay on it, is my favorite part of this track! The reverse sounds are also a very cool addition. The transition to the darker sound and then back again to the original calmness is a nice arc to the story of this track.
The Power Grid: You did everything that your description says you were intending. The space and the deep bass notes with the constant rain certainly makes this feel ominous and like a pre-climactic/climactic track. My favorite part is the change in feel slightly with the long violin and the piano ostinato at 1:39. This gives a different kind of forward momentum and energy that puts me on the edge of my seat.
I’ll See You Soon: This is so calm and serene. The wave ambience is nice and the guitar seems to swell like the waves too. I at first couldn’t even tell this was a recording, it sounds so good! You do a good job with poignant emotions and I think bittersweet is a perfect word for describing this track. It feels like Engie both lost something and gained something.
Overall: I think your full soundtrack nails the theme as there are summer, water, electrical, and night time elements to the music, and it creates a story with excellent gameplay mechanics. The highlights for me were the ways that you described very specific emotions through your music and the flow of your music tracks. Great work and thank you for sharing!
