i've done that one already, i don't have a recording though. great stage, had a lot of heartache with her criss-cross heart patterns, she's a scary one for sure
i recommend starting with the early windows games, so from 6 and up. embodiment of scarlet devil is good difficulty-wise, but it's a bit primitive (it has no hitbox indicator and the stages are weirdly balanced), so if you want a bit more modern then 7 is better. you can try to surf games a bit after getting into it, but i recommend going for a no continue-clear (1cc), it's a lot of fun
