if you want to install this on linux or on a chromebook (whatever you own just make sure its linux) install linux beta. then install the linux zip. drag the zip to your linux files. go to your linux terminal. copy and paste this
unzip RERUN_linux.zip
then you have to wait for it to load.
then type in this command
./RERUN_linux.x86_64 --disable-framerate-limit
it might tell you if you want to continue so just type y and then press enter.
and make sure it says
"Set current directory to /home/insert your name here or email
Found path: /home/insert your name here or email/RERUN_linux.x86_64"
and then play rerun, drink milk, and stay a boner.
hope this helped :)
EDIT: you can close RERUN by right clicking on the penguin on your task bar and press close. and if you press close and want to play again youll have to type the commands again which is a bummer. so make sure to wirte the commands on a doc or on a piece of paper
