@delator77 I was going to throw in a couple more mechanisms, but I'm still figuring out how to get them to work properly.
Very linear - 'follow the ball' BTW, the 2nd last ball isn't required as B doesn't need to go over it. B could also do a ToA from the landing just above where B starts and skip the 3rd ball too.
Three for the game play +1 star for the nice balance and decorative architectural touches. Is it linear? Sure, but so are a fair share of the original 50.
+1 star for being playable +0.5 star for no shortcut +1 star for the nice design +0.5 star for the easy gameplay
