Are you using a PS5 controller or xbox? Its back on xbox and share button on PS5. Thank you for playing!
I was using a PS4 controller. I didn't see anything specifically saying what the restart control was.
Try the share button and let me know if it works; I dont have any playstation controllers so I'm trying to discover this myself.
It didn't work. I made sure to test every button. R1 and R2 both just went back to the level select though.
