Oh boy, I had to mute the music; I think I get what you were going for, but it was just a bit too psychotic for me!
I enjoyed the platforming, the jumps felt good! I did however not enjoy dying from touching the edges, and doing it even in the "hub world" felt like a bit of an oversight.
I would also have enjoyed not having to walk through the entire hub world every time i left a stage.
But I will freely admit it was a bit scary to be chased by those big marshmallow-ghost-thingys, and it looked game boy-y!
