The pixel art is rather well done, and the realm shift for the shadow theme is nice for puzzle interactions.
The movement is a bit clunky in combination with the animations, like attacking and moving at the same time.
I'd also say that life force and health are very close together in regards to concept and color on the screen. Maybe if they were different colors they'd be easier to distinguish.
Oh also, what shrub/bush/mushroom is an "enemy" and what isnt is not very clear.
It is playable which is good, and the style is there, so keep at it and it could become something really cool :D
