NSMB - Mario Vs Luigi Online
What is this game?
A standalone 2-10 player remake of the Mario vs Luigi gamemode from New Super Mario Bros DS.

Install instructions
Make sure to extract all files out of the zip before running.
Mac users might have to disable some code signing or verification thing? I'm not exactly sure, I'm not a mac guy. I'll get some specifics soon.
Linux users have to make the file executable, using "chmod +x linux.x86_64". You're running linux, you can probably figure it out.

I have a home computer lab in my basement. I want to play NSMB on the computers and I can host a game and connect with the first client but when the second client joins I get an error saying, “You are already connected to this room in another instance of this game.” Any solutions?
playing on the website or the app makes the owner of the room get all laggy, on the website other players also get this effect
for some reason Cory just banned me saying "friends only" like hate that guy

it would be so cool if we could add our own characters and send files
and turn back the main menu and the matches into the mario vs luigi when it released.
can you add voice chat?
Is there any chance for adding mic features to the game
Merry Christmas guys!🧑🎄🎄
itch.io servers are breaking
well for one thing
the only thing worse than that is not being able to play* the number one** platformer in all of itch.io.

Hey guys I made a group on "OMEN" it's some kind of forum thingy idk but it's not made by me
Here's the link: https://cubedz.wixsite.com/omen/group/nsmb-mvslo-nsmbvs/discussion?origin=onboar...
There seems to be some kind of controller input bug in the browser version: when I use the controller to go to "Hide in-progress rooms", the controller input suddenly stops working except for the "back" button
can we get some justice for coin runners

Ipod, can you make it so you can't mute someone in a room unless you're the room's host? Also, the meme reset is happening at the very start of 2026. (1/1/2026 / 1/1/26)
Please add the super leaf, it's one of my fav power ups...
