I guess this only makes sense in the context of consoles, but I think it would be cool if there were some game where every move was made up of combination of buttons pressed consecutively Like if walking just wasn’t as easy as moving a directional pad but required some complexity
Not quite what you're describing, but for novel control schemes and novel movement schemes in particular, Both Ape Escape (1, 2, & 3) and Steambot Chronicles have specialized movement schemes when in vehicles / steambots where you move with a combination of both control sticks, for example left + right stick forward to move forward, left stick back + right stick forward to turn left, etc.
that's usually called "tank controls" if you want to find more of it, it's as old as Battlezone (maybe even earlier idk)
