Like for instance, even you and some other members of the forum said that you think Karate Joe would be the RH character and others I've seen mention the Tap-Trial Girl.
But no one really visualizes or discusses them, so I feel like it would have to be them.
Oh, you mean implementation and moveset-wise? I’ve thought about that!
Obviously, the concept behind Joe is rhythmic combo-ing, which could be a part of any Rhythm Heaven character.
His basic combo is a simple punch, but if you do it twice and then a third punch at the same tempo of the first two, you do a much more powerful third punch. This is a reference to Joe’s 3-Hit Combo from Rhythm Heaven.
His Forward Tilt is a roundhouse kick, like the type he uses in Rhythm Heaven games. It’s much more powerful if you do a simple punch first; a “Punch-Kick” combo.
Those are the only specifics I’ve ironed out, but everything follows that pattern with the basic moves, which also include Joe’s sweep kick and uppercut.
Meanwhile, Joe’s Smash Attacks, Specials, and possibly Aerials are moves that reference other Rhythm Heaven characters/games, which I think could be accomplished by any RH character.
However, one of Joe’s combos is stronger and does more knock back than his Smash Attacks.
That’s what I’ve thought of.
