Ghost Push Blocks

[gemj]

This would be immensely confusing (in terms of visual) but I think the mechanic idea is very cool
I don't think they should be ghosts, but rather just another block type that kinda looks like a push but also looks like "I can't push this myself" maybe like a push block with a chain on it or a metallic crate looking push block

I like these ideas! I'll add that I think the little circle that we see on the yellow push block should stay. little bit of continuity I suppose.
