This game has always interested me b/c playable Bandana Dee (with a unique moveset!), but I've never gotten around to it because I have no real PC controllers other than the dreaded keyboard, not to mention that I share it with two of my siblings so I don't get all that much time on it.
Guess I'll just settle for my Bandana Dee skin mod over Kirby in Smash Wii U for now.
Playing with a keyboard is doable, it just requires A LOT of time getting used to, at least from my experience. Dashing is another input. Smashing requires another input. Jump is mapped to another key.
I tried playing with a controller but it feels off, and inputs don't read very well at all. I had more responsive controllers in Smash Crusade.
