New mechanic

Hi there :)

Recently I was bouncing my head around the idea of better mix-in snakes length into the game mechanics. There is already a mechanic of opening doors with larger snake, but it wasn't enough. I needed to add something else. So I came up with this solution. 

Each object on map is blocked and can be unblock by eating proper dot. Unblocked items can interact (with snake or other items), but blocked items can be pushed around the map. If you stack few elements next to each other they cannot be moved. Unless snake has proper length, like in this GIF:

What you think about this idea? :)
