I would like to tell you that the game runs fine. Combat, as you said, is kinda cluncky and hitboxes feel weird but apart from that, you have done a great job with the move and the fighting system as an idea. Most people say lack of content, but having tried game dev and I know that this being a new game made by one person is understandable. Jotaro's model could use some more love but with time everything will be in place. I loved it so far, don't lose motivation, know that this is a good game
(Pls add the part 7 main cast I beg you ill do anything, ill learn c# to help pls add them! XD)
