This is a video of me, Tasselfoot, beating all 24 free levels of Hippie Phuzzle by my friends at Spelgrim. I'm aware that my solutions to 23 and 24 are not the "optimal" or "planned" routes... but as shown, they do work. I'm also not really sure what I did on 20, but it worked eventually too.
20 and 24 are on 2x speed.
