Space Case 2 is probably the easiest Space Case Stage.
It begins at the top of a slope. At the end of the slope, you can jump to a nearby platform that leads to the top of the level.
Or you can drop onto another slope, which goes into the mid part of the level. Either way, you need to roll across several moving platforms that have bunches of bananas on the edges.
Then you proceed to a final, bumpy path. The goal awaits at the end.
