Thanks for the review, especially the video, it is always helpful to see others play and things I can improve.
Story is coming! I will be looking to build out some character back stories and flesh out the plot very soon. Might be a while before its actually in the game (or demo) though. Music is mostly placeholder at this point. As you mentioned it also needs some more dynamic event music for fights etc.
Interesting points about the mouse. I tend to develop/test a lot with mouse/keyboard as it is quicker but I do have the dodge key mapped to my side button which helps a fair bit. I might need to reconsider the defaults.
