Running an open-source project on heroku

I am trying to run HabitRPG on Heroku because I don't have root access in the machines in my school's library to install the dependencies.

The wiki to HabitRPG gives instructions on how to run it on a localmachine, but does not talk about running it on Heroku. I understand that HabitRPG used to run on Heroku, but lefnire had to move it.

What am I facing here? How much work am I looking at to run on Heroku? Have they not given instructions to deploy it because they don't want people to? Any help would be appreciated.
