Overall really good.
I would make it a little clearer where the links are, I know it wouldn't be realistic for them to stand out more, but it would really help the game feel.
Sound effects when walking would be appriciated.
Some levels felt very very trial and errory almost like a meat boy feel and I'm noot sure if that was intentional or not.
I really liked what I presume to be an ad for your steam game within the game.
