Swtich from remote play together to parsec.
It's way, way better ( I play 3/4p and no issues so far, though lag would occur at some time during endless, like in solo play ).

Probably because of how much work it would be (a whole lot) versus how much of their player base they expect to care about any kind of multiplayer (very few; the game has been out for years with only single player and was doing fine).
