Really wonderful little experience, and a very creative way of using the limited Bitsy game engine. I enjoyed it. The visuals and animations are great. I really enjoy that the main scene changes throughout the story and use different color palettes to set different tones on the same scene.
I think you should add collision boundaries on a lot of the tiles though because walking through walls inside the lighthouse and also walking to the clouds and moon, etc - does break the experience a bit for me.
