I liked it! The movement feels good, though it would probably be more satisfying if you could punch without letting go of the sprint button. I see a lot of potential for fun platforming movement to be added, like airdash punches, downwards punch (stomp) attacks, maybe even a grappling hook using her tail. If you keep working on it, I could see this becoming a fun retro 3D platformer! One other small thing: maybe consider removing player collision on the rock pieces after you break them, as it can feel a bit janky getting stuck on them.
