Spoiler: Tricks SSS Low Ceiling/Claustrophobia Autopilot Bot stack If you see more tricks, comment below.
Found two ways to win. Both similar but one gameplay didn’t use the ball above R. Interesting looking level.
@Blue Tower - Are we talking SSS or SBS? After the first ball drops, then B goes to that ball right? That is Stairs SIDE Step.... EDIT - That would be 2nd ball as I didn't see the first ball until after.
The larger tower didn't have much purpose and the level was fairly straight forward. If SSS wasn't required, then I did it wrong.
Enjoyable. I found a little shortcut, not using the ball over R (or SBS). Spoiler B can ride the other ball down to the hole next to R, by using the slider to push it.
Cool looking buildings and some fun moves for B . Tried the shortcut mentioned by @ridgerunner and @cimarronline which needed skill ! Also agree w @Ray Aznable .... the fun and adventure ends too soon !
