Pretty solid overall, Breezy village is a map that isn't super crazy but pretty cozy and enjoyable anyway. Delfino Coast is kinda just ok but has some potentially big balance issues with its capsule and tripwire placement. Frutiger Aeropolis has a very strong theme i like alot with only one kinda trouble part, otherwise having a nice layout. Retro maze is ok but suffers from sorta poor readability.
More details in the discussion tab. Otherwise, solid stuff all around, playing Master mode GP on this was tough but fun.
