Great game. I love a tough platformer. The music was really nice and I thought the visuals were really cute too. The level design was great and I thought the idea of only showing parts of a level was a great idea and implemented really well.
I think the moving obstacles were a little hard to track in the changing scene. Maybe some particle effects to show rough location or giving the player the ability to control what they can see may help?
I would also suggest for any platformer to read this thread by the creator of Celeste. He talks about some game feel things like jump buffering and coyote time that make a character feel better to control. Just something to consider :)
