This game was meant to have a GameCube sequel, but it was renamed Roll-O-Rama with a plain marble in Kirby's place and then unfortunately cancelled in 2002.
This game features the following tropes:
- Bottomless Pits: Kirby will be knocked out if he falls off course. Despite being able to float. Water and sand also count as pits, though you can float over them for a while.
- Everything's Better with Spinning: One of several spinoffs entirely dedicated to Kirby's roundness.
- Excuse Plot: King Dedede is building marble courses for some reason and Kirby gives chase, suspicious of him being responsible for planet Popstar losing its stars.
- Gotta Catch Them All: Each stage has hidden stars that can unlock certain secrets.
- Level Goal: At the end of each stage is a target which Kirby must land in the center of for the best prize.
- Oddball in the Series: Main Kirby games are platformers where the hero can use his enemies' own attacks against them. This spinoff is instead a marble run toy akin to (and, ironically, considerably better than) Sonic Labyrinth.
- Platform Hell: The game gets pretty tough with later on, as you need to carefully roll Kirby along narrow roads and obstacle sequences surrounded by pits.
- Recurring Boss: Most of the boss fights are against an Orbservor, a giant eyeball.
- Rolling Attack: Kirby actually cannot attack just by rolling on people and has to either flip enemies or bounce off them.
- Springs, Springs Everywhere: Because the game is largely based off marble run/carrying toys, several levels have chains of launch pads you must carefully bounce Kirby across.
