Thank you for playing! The multiple weapons exist because of the hack 'n slash nature of the game, which purpose is to use your arsenal to the fullest capacity to get a better style score, although it is true that the moveset is essentially the same for the two weapons. The original idea was to make the axe more focused to crowd control while the claws were focused on burst, but the idea didn't land quite well haha
The dash had to be different to the hoverboard due to both of them serving different core purposes, but it certainly could be simplified.
Thanks the feedback!
