Sorry, I practiced bungee today on that map, but then realized I had a wrong scheme :/ It has 10 seconds retreat time. But I suggest to approve that run, because I used retreat time only once and it was obviously less than 5s.
I know, these challenges are old, but I found bungee is so fun and it's the first day after 2 years I played it last time

And this map is the only I can finish in an acceptable number of turns so far ^^ Thanks
