Yeah, it's better to use a controller. What keys would you recommend? I don't play many games with keyboard so I'm certainly open to suggestions
For me personally:
Direction - WASD
Sword - K
Jump - L
Copy - J
Equip 1 - U
Equip 2 - I
Menu - E/F
Note - Q/R
The habits of players using keyboards are generally different, so it's best to have customized settings, but whatever the method, I personally don't think it's good to assign an action key on space when there are complex keys.
