The storytelling at the beginning is super cool and the art is gorgeous! And I enjoyed the dark level idea. Unfortunately, the game was too short, I'd love to play more levels. I have some observations that you can take into consideration if you're willing to keep working on it: the jump sound is a bit annoying, the fade out after completing a level didn't cover the upper part of the screen (the gap was small, don't worry), the bar you have to collect in the dark level shrinks in one dimension and grows in the other, so the bar may disappear before it completely shrinks.
