Here if how it goes. If you have a scratch account remix the previous project as something nice for anyone with a scratch account. Send them a link to it. Have fun! Go in regular mode at the start, then into turbo (shift-click flag) once the hallway disappears.
I remixed the project to make it for http://scratch.mit.edu/users/dr3w8/ Go check him out! If you want to take the kindness challenge, go to aktion258's project!
