Really enjoyed the art and the music here. Made for a cool atmosphere, and the different tracks were nice to hear. I don't know that it utilized the theme in the concept or gameplay.
I think the hit box range for the short attack as just a bit too short and I would have liked a little bit more speed in the movement. I like the approach of "avoid filling the danger meter" as opposed to dying/taking damage, though I think it would have been cool if the game had a stealth element where you had ways to use the wall launch to find secret paths to sneak past the enemies or something like that.
Has a good foundation that I think a lot could be built upon to make a really charming game out of this. Good job!
