Forest Cantical: I think it is spectacular how you conveyed nature through synths alone. This does an amazing job of musically supporting your story themes. I really love the reverb that you use and the slight detuning that seems to represent a little decay. Very nice opening theme!
The Three Sages: Your use of big bass pedal tone supports the story-telling aspect of meeting large trees living within an organically mechanical world. This theme is contemplative and pairs so nicely with the cutscene you created. Very pensive and beautiful. The emotional shift and energy charge is well-timed and so reminiscent of the era of music you are emulating.
Bacchus The Augur: Those big braams are an excellent way to start this track. The clarinet sound was a little unexpected, but I think paired with the big drums and low braams does a nice job showcasing the organic + mechanical power of this boss. It feels natural and plant-like. I think for a final boss fight, I wonder if more rhythmic high register elements could have been added later in the track to add a sense of high energy danger, or if that would even work based on your idea.
I like this collection of tracks and your dark game idea a lot! It certainly conveys the theme of an old forgotten world and makes the story interesting and intriguing. The animations you made also added to the overall experience in a very immersive way. Great work and thank you for sharing your music!
