Can't get past the 4th level but I really like the gameplay.

Yeah, that level is a massive spike in difficulty. I've seen two ways to do it with one being much easier than what I intended. My hint is that you want boxes near you to push onto the button while standing near the portal. I really liked your game with its duality mechanic! (Probably not the right word but I'll go with it!)
