Really really gorgeous game, and simple to understand and play. It's cool you've added a preview image to show what the characters look like.
The controls are a tiny bit too sensitive to properly navigate in the area. Another thing I had is I got softlocked in one of the houses because the monsters inside would block my way, and one of the golden keys inside the house wouldn't unlock the next door, so I can't reach the end if there is any.
But still, good job! And hopefully we'll see fully fleshed out version in the future :)
