I've been meaning to comment on this for some time, and finally got around to it.
Definitely something unique here, but not so much of a ufo for anyone who have been listening to japanese VGM for the last 20 years or so.
Haven't seen the game in action, but even without the context, the minimalist approach clearly has its charms.
I think the harsher comments may have come from the fact that most people are used to the canon of saturated soundscapes,
complex melodies and full range of instruments fighting to conquer the listener's attention.
From my point of view, this is a breath of air. Maybe not the freshiest, but at least one that let you take a break from all the generic orchestral-choirs combo,
symphonic rock and other industrial electro/pop driven soundtracks.
Favorites tracks are the groove-based, delightfully nostalgic and joyful Old Oddities, and the evocative Looking Glass with its enthralling synth and bouncy percussions.
Most pieces though resonate with memories of classic gaming music, but have a personality of their own, with this distinct chill and lighthearted sound direction.
The Kaleidoscope soundtrack manages to efficiently bring together entertainement and nostalgia in a very candid way, and with such simplicity that makes it beautiful.
Thanks to AnSo and djp for the ride.
