Catch the wizard

@cpw The weird flying of R is reasonably stable, but depends on a lot. I also tried to let him land higher up on a grass block, but that block itself influenced his flying, or mostly prevented it. Also the guide rails/blocks for the balls; if I change one block in a rail or the other way around, or add one, R will probably not go into the air. So in the end I left it mostly as it was when I discovered it. I think I only changed material, but no shape.

Amazing level, I really had fun with it. Thanks!

Spoiler: Shortcut

If B goes up following R and got on the second ball behind him, 90% of times touches R head/win.

@chemi If... indeed. I think it's quite difficult. Bonus challenge.

Wow !! Great !! I confess that I have completed 3 times because Winbot (jajajaja, I like it) stumbled with a ball and was activated accidentally .... after I tried to follow the path that I thought correct but never arrived on time and I thought: I have to go faster, I have to go faster, I have to .... Jajajaja.... Until I read a spoiler from @Chuckthulhu and everything has changed .... Brilliant @Block builder , especially the final step ... THANKS

Fun whimsical level with an intriguing backstory that's sort of meta.
An elusive wizard with an impossibly grand entrance (!), a chase scene and disappearing paths, what more could you ask for? Am not too bothered by the win box getting activated accidentally at times, no s kin off my nose. Thanks for this!
