I understand I'm bad (especially since my prediction ability is as decent as a fish on land) but I don't get WHAT it is I'm doing wrong, or how. And I don't understand what it is I can or need to do (like these weird spin dash things or how this guy manages to time his blocks perfectly against all my moves)
