Round trip

Extremely slow start as B needs to wait for zapperR to pass. Since you didn't provide a recovery points, one slip and you get to restart over and over. I lost interest especially when B needs to do it twice.

Hola y bienvenido!! Buff your second level? Fun logic/ability level with nice path...To be your second level I see that your construction is very worked(I'm really stucked in your first level,too many elements and difficult path...give me a couple of days) I had fun but I have doubts if I did it right because I didn't use some elements of the level but my path was a clean logic one,without using tricks...I'll do a movie to show you my way...Thanks for sharing and well done @j.marques

Well,the level is long and I haven't enough space on my phoneso I'll do the movie in two parts,ok?

Well here is the movie...

Spoiler: First part

It is not necessary to do the second part because it is exactly the same way but in the opposite direction ...
