I'm usually not much into ambient electronic stuff like this, but I thought this was done fairly well! It kind of felt like an orchestral suite but with every instrument being a synth instead. I appreciated it. The Maintenance System was my favourite track: It had this really eerie vibe that none of the other tracks had, and the electronic sounds in the background really helped in selling the "abandoned lab" theme I got from the story. The first track's mix of guitar and synth also left a really great first impression. Is this meant to emulate or is inspired by a specific genre? I've never heard of something like this before, safe for some botanica songs in my playlist.
I enjoyed this submission's story a whole lot, it interpreted the theme in a fascinatingly unique way, and I like how the Symphonia wasn't portrayed as good or evil, but simply as an organism trying to survive and thrive the best way it could... I'd love to witness a bigger version of it, I honestly think it could work well as an artsy movie with few and far between dialogues.
I think something like this could work really well in an actual game, letting the player fully blend themselves into the environment. That's not exactly easy to achieve, One might get too lost into adding a lot of fluff to make their songs more interesting at the cost of distracting the player from the game's intended feel. Hats off to you!
