*raises hand* While the instrumentation is definitely weird, I don't think it's bad. I think it hits the "fine" benchmark. This is largely because Carnival Night's original (Buxer) song was gutter tier trash, but I digress.
I think the production on Carnival Night and Launch Base is way worse than the other tracks on the OST, like alarmingly so. Ice Cap fares better for some reason, but it doesn't fit the vibe of the stage at all imo. I'm not the biggest OG Ice Cap fan (Act 1 is good imo, but feels like maybe 2/3 of a song), but it's extremely hype and has an infectious melody and bassline. Prototype Ice Cap is way too jolly when I want it to be cool.
