to add my feedback: i really think there should be an option to move in game and navigate menus with only mouse/only keyboard. now you need both and things like choosing perks or using store is unnecessarily annoying. small thing, but it would improve the whole experience by a lot.
same with how sword works, unnecessary mouse aiming, while it could just attack in the direction you are facing.
oh and these big characters on the screen are great, but as gladius have said, making them lose clothes as you get hit would be amazing.
