This is such a fun soundtrack! "Our Peaceful Home" and "Cozy Town" really sound like they'd fit in an early-gen Pokemon game, they're so sweet and nostalgic sounding, but also really full and dynamic.
I think my favorite track has to be "The Forgotten World" though, it's just so exciting! It sounds like running around in a big exciting world, maybe even racing game energy.
The gameboy style box art and the story idea are both super cute too! The story really gives me Cardcaptor Sakura vibes haha. I've always thought a Cardcaptor Sakura style collectathon RPG would be fun.
