Are there any tips and guides on beating the boss? All I know is from the start we should attack the boss from the back so the boss didn't attack but that is all I know. Anything else to attack him nonstop?

Ok so some tips I've found, the more you play the more pattern you will recognise. For example: There is one attack from the boss that attacks 4 swings before he/she stops.

well you can't attack him nonstop for one simple reason: random. yeah so basically when you start attacking him he can dodge or decide to attack you directly, if you are lucky he will attack with a simple slash allowing you to quickly dodge and start another combo, less lucky he dodges and you pray to do a simple dodge and not a roll to be able to attack him quickly enough to stop him to attack, not lucky he doesn't dodge and start a 3 hit combo, even more not lucky, he doesn't dodge and start a 4 hit combo

also sometimes like in my 1m29 run if you try to be greedy he can just start to dodge all your hit and just make you lose seconds for pure fun. except that...

I don't know much I just started yesterday

also I think if you hit him fast enough when he doesn't dodge and try to do a combo you can stop him sometimes it happened to me but not sure about that
