I'll take liberty to not fully agree with Shinichi, since imo it's one of those kind of songdongs that don't really need to be overly varied, i feel like it's deliberate style choice and everything seems to be in place, it's just maybe a bit too long, but i still find it a good chill track to have running in the background, and not grabbing all your attention if you want to focus on things you're doing rather than on the music itself.
As for the bass thing, it sounds like there's a stereo ping-pong delay effect thrown at it, and it's a bit too feedback-y
All in all, good tune :3
EDIT: I just read the description, turns out like not everything was a deliberate decision, since Tiido has started right before the dedline, lol
Still, good tune
