Awesome mechanic with a ton of potential! The level design was really well designed and well paced (the only spot I had trouble with was the final key up high, skill issue). Clear visual language with the lanterns bright purple makes the level understandable. Lots of polish in animations, screen tilt, fog, etc. Well scoped, too.
I hope you go back and turn this into a slightly longer/more polished experience because I would love to play it!
