Simon and I appreciate the kind words about the soundtrack! My background is in Touhou-style music as well as Dodonpachi, so yes, you're definitely hearing the Japanese bullet hell influence.
No worries the praise is well deserved ^^
Dodonnpachi, the Touhou series, and even a bit of BlasingStar are definitively what came to my mind, and even though i’m no expert in these types of games i always apreciate their ost’s and yours really fits right in the same style with the same level of care to it :D
