You could glitch it in the past. I know that especially with the new update it bricks. So I'm glad it got fixed. But I wish there was a way to have this and it would automatically detect 2 players so it would respawn items that are needed. Or a way to drop items so they could switch maybe if needed.
I know that these issues will probably fixed in a later time. Especially if there is online play. There was a lot of fun trying to do runs of single player stuff and using mechanics like throwing the characters around to not brick things. It forced new ways of gameplay.
