Really upbeat for something that's toned-down. It's not flamboyant as someone would try to predict for a shoot-em-up game soundtrack to be, instead it's *calmly* adventurous.
The vocaloid samples are a high-tier big brain move because with a game soundtrack having it loop with coherent words would become EXTREMELY repetitive, but in this case, the vocals have gone through so much autotune or distortion that it becomes a harmonic instrumentation instead. Very solid concept with correct pacing and switch-ups and subtle piano solos and really reverb-y synths that pull the air of being fantasy-driven very cleanly and stylishly.
A hella nice bop~! ^^
