Can you install one of them or you must install all of them?

i played this on my xbox serie s. oh my god pac in time is complete garbage. i found it impossible to pass the first level which means you can't unlock another game by playing it twice which means finishing a level twice. the controls in the old school pacman games are horrible on anything but a joystick but that's nothing new.

this could be very nice for a mobile
but for PC meh
