Challenging but not impossible. Generally user-friendly. One of the steps near the end is interesting and only found it by accident. Spoiler: Ball instability One of the balls is unstable as it sometimes goes into the hole and sometimes not.
@Ray Aznable the last step is a bit unstable. You need to stand on P and go to drop the highest ball before this b need to stand on that ball
@Anomynous Actually, that's not necessary at all. Spoiler you can have B ride P around the outside edge. Once the balls are in place, the wedge will push B off of P and onto the ball, so he can use the corner structure.
: @Don G Rowe the way explained by anom considered as special effect alternative. fun to watch it tho.
I got there finally, ! I needed the hint from @Don G Rowe to get that move near the end. I was ages with all the balls in place, trying to think how to get up onto the corner structure, !
Got it now - same ball order, same basic gameplay... hadn't thought to ride P in that manner, and B needs a quick tap to avoid falling off the ball, but it works.
I had a go at the @Anomynous way. It's a lot of fun, but I think B found it too scary, ! He just keeps falling off,!
