Very cool! Let's go with my impressions:
1. Where Did I Go
SHAKER!!! Forest vibes all over, lively, loving the kind of woodpecker at the background. The percussion is fantastic, and loved the tastefulness of everything and the distribution of everything in the mix, with the motive central, with the piano on the side. The last syncopated chord works great to spice it up.
2. Sitting in Between
I had to check if I was listening to the same song in repeat. I think the motive sounds too similar to the first track, with no variation in timbre, tone or rhythm. This is detrimental to the listening experience, as it inevitably feels like a repetition or modified version of the first piece. I am digging the alterations in the soundscape backing the melody, but would have loved for the melody to also morph into something different (or maybe disappear altogether and make a comeback at the end of the track).
3. Emergency
Same issue with the repetition of the motive. Badass drop and transition at 0:40. That panned, overdrive line is killer. Loving when finally the Dies Irae finally starts to blend with the rest of the song and loses its protagonism.
4. The Worm
And here we are freed from the chains of the motive, for once and for all! Loving the flanger and wah. For me this is the track that hits harder.
5. On my way
Awesome textures, taking me to this earthy, raspy, dirty soily ground. The drums programming here is top notch. Hypnotic percussion with great sound design. Also the general layering is very good. The only thing which kind of bugged me was the timbre of the lead, getting a bit shrill with the repetition of the melodic pattern.
Great work! I am loving the concept, and kudos for the artist who created the cover! Beautiful and powerful, transmitting this mood of earth and wood and wetness and dark soil, fitting very well with the textures of the soundtrack and the video game idea. I loved many things in your pieces, and I sometimes just wished for the Dies Irae to be less central and make room for other original melodic ideas, but of course the idea of the jam was to use the motive, so nothing to say in this regard! I might just be starting to feel tired of listening to it in so many pieces, including mine...
