The art is simple but visually pleasing. The environment is maybe a tad bland but honestly kind of works with the dreamy feel when the music is playing with it. The characters look neat, I like the night a lot.
Somewhat of a nitpick, advice I've gotten before has been to make things the player can't do (at least yet) more obvious. At certain points I kept trying to get onto certain platforms before giving up after realizing I probably needed to unlock something to get there; if they were obviously to high or far for me to jump it'd be less likely that I aimless try.
The SFX were a nice touch too, like when the crow attacks or the walking sound of the knight or the squish of the player.
Nice entry.
