Turns out for my laptop I had to download player select mod and then I had to go into a level and switch there. Sadly player select mod doesn't work in Vanessa's curse so I can't play as luigi there ,but I don't really mind.

You...can? That's how playable characters are supposed to work. Once you switch to him either in the lobby or from the player select menu mod any playable character should transfer over to whatever level you're playing.

kinda wish you can use him in levels
