The 2D version of the Dark Forest

Would the Dark Forest be the de facto rule of the universe in a 2D universe too? With no height dimension a big enough radius would essentially have stars and planets blocking the horizon all around you, the only way to observe past it is to look for slits that open at certain times during orbit, or blast away the blocking bodies layer by layer to reveal systems further out. I might be wrong here but it’s an interesting thought that 2D might actually be manageable and longer lasting than the higher dimensions.
