i tried to use parsec to play with friend but they were not able to control anything we tried the assign controller part but it did not work as the start button was not working is there a fix or any other way to do something similar?
player 2 by default has no key binds for the keyboard and has to manually make those in the settings menu (the cog on the bottom left in the title menu). Go to 'controls' -> 'keyboard' and from there you can bind your keys. Make sure you have a key for jump and roll as that's the confirm and back buttons.
