These maps are pretty ok overall.
The Basic Cup tracks overall are lacking in decent shortcuts (save for Aqua Cave with some offroad cuts and a really strong end-of-lap cut that cuts 6 - 11 seconds of time). Beside that, All of the tracks are mostly inoffensive by themselves save for some points.
- Aqua Cave has some Z-fighting moments going on alongside walls that have the Grasswall texture. Most notable at the first turn and the wall where the strong shortcut is.
- Mirage Monolith's quicksand timer hazard at the end doesn't have a reliable way to know when it's going to switch sides if you didn't see it switch as you round the corner, leaving you to hope that it doesn't switch side as you make the jump. It's a near-instant switch between sides with barely a second to adjust if you're near the ramp which is why I would suggest slowing it down or giving a visual warning that it's going to switch.
- Sunny Garden has a lot of Sneaker Panels yet no shortcuts, which makes Sneakers and Rockets pretty weak items to get. The big hedges with intense shadows (like the one at the first item set) can also slightly hide bananas from sight until you get close enough for them to get you.
- Aerial Sanctuary, like Aqua Cave, has a really strong end-of-lap cut. Not as strong as AC, but still pretty strong to warrant checking out, I'd say.
