Nice beginner effort here.
For feedback: Some background music and sound effects could help reinforce the environment you've built. The very detailed art style of the characters didn't match the background, however, they did pop out a lot. Nice to see the characters have some animation. The action indicator used was easy to miss, I think the color doesn't stand out very well. Good practice using scene changes (or canvas/camera swaps). On the scene changes, I was able to walk to the left a very long way and then took same amount of time to return to screen. You can use some position limits to prevent character from moving too far off screen.
Short and sweet story pulling together a lot of game making elements.
