Hi there! :D
Gave both tracks a listen. Your sound was definitely not something I was expecting, but that was a good thing! Both tracks are minimalistic when it comes to instrumentation but are very moving when it comes to pitches and rhythms. Also, I like the tonal ambiguity within both tracks, particularly with "Nemutai Bubble Girl OST" one. The structure and melodic aspects of both works felt weaker than most (or what is typical when correlating a theme to a any specific track from a game), but that's not too much of an issue. Wish there was more material to listen to/further develop what you have here, but overall it's pretty good!
