Very cool compositions!! I listened to the last six you posted. I can imagine them in some games, though with the few I've played, I can't properly give an idea...
Bright does make me think of a sunny day, even if the scenery might be a bunch of blocks or metal parts. XD
Channel makes me think I'm going through some creepy corridor/cave modified by technologies, but dark and...just eerie.
Dark...that one's harder to explain. Feels like I'd be in an underground neon city, the lowest streets and areas with fewer flashing lights.
Ahhh, don't want to overwhelm with my descriptions of my thoughts on the songs. XD Just one thing...I like how Stereo is the "sibling" to Momo, I can almost feel that in the song.
Hee hee!! Really cool job! You're a great composer!
