What is this place? Don't know, but at least you'll have a clear sight of where the road wants you to go.
Polychrome Polygon Zone is a returning track from SRB2Kart ArcadePak, present since it's first release but being tweaked up a bit since v1.5, a somewhat simple 5-lapper decorate with flat-shaded visuals and a fair mix of straights and sharp turns ending with a high ledge where you can triangle dash off.
