We need a name for platformers with fluid movement where instead of having a few different discrete movement abilities player can use with consistent timings, character movement is instead directed by various states and doing same actions result in different moves.
To elaborate, imagine a traditional platformer like sonic: you have a singular "main" state and you plan your movement with an assumption that after doing something - you will return into that main state. i.e. i roll into a spring that launches me forwards and then do a ground-pound because i am no longer rolling to get to the ground quicker.
And now there are games like rain world where instead of plannig around using discrete moves, you instead plan around being in particular states. Instead of just "doing a slide" you go into a sliding state and then decide what next state you would want to be in: going into a pounce, a pipe slide, a whiplash or just resuming a crawl - each one of those also having multiple "exit" options.
Here's an example of a demo that has a similar system with pretty fun movement.
