correct me if I'm wrong, but there currently is no hard mode. with the introduction of a hard mode in the future, there may or may not be a chance of extra accessory slots? I kind of like the Idea of resetting once you complete the game, earning some sort of pionts and unlocking such things as extra slots, invintory space, better stats ect.. while the game gets harder.
in the end, im happy i got to play such a nice and fun game, Thank you
