I really want a guide or walkthrough like to show me where the the weakspots are for this type of minigame on this site or wherever else you put it.
Just a food for a thought.
Maybe not what you were expecting, but there's a guide for the boss weakspots here https://steamcommunity.com/sharedfiles/filedetails/?id=1868890259 It might not be perfect, but I think it shows the general areas of the weakspots. There's also more complete guides for the game there that include the bosses in one of their sections.
