This is so atmospheric and nice, I love the music and how it's presented. Also smart way of implementing the tutorial and setting up the motivation with the graphics. I was impressed by the start of the game.
Sadly I got stuck in a wall and I did not want to restart, but may try again later. I would suggest changing the game design a bit (more guidance in first part of level, do chackpoints as dying was too annoying, coyote Jump / be more forgiving if player jumps close to an edge).
The atmosphere and mood in the game is so great! Very nice composing and style! Impressive!
