Fun game. Tight gameplay and long enough. Not a fan of combat though. Attempting in sword fight means you'll lose half of the life anyway, so it's best to avoid them. Dash attack partially helps but it's not a one-shot kill either. Perhaps a ranged weapon option could help so that you could throw the sword at the enemies. Some chiptune in the background would also benefit the game greatly I think, something that goes in sync with the jumps.
