Looks very similar to my tool, tere: https://github.com/mgunyho/tere. The main difference seems to be that I don't do any file manipulation, while walk has the option to delete files/folders. In my implementation, you don't need to type '/' for fuzzy search, just typing searches and jumps by default.

I also have a list of similar projects at the end of the README, I'll add this as well! edit: Oh I already had it in my list, the project has just been renamed from llama to walk.
