I see that is not update and not sure it works with the last version of CiviCRM, do you think is a dead project? is there an alternative?
CiviVolunteer has limitations I've found that unfortunately do not make it that user-friendly. My use has been with Wordpress, and there are conflicts with it on the front-end. I would consider it almost dead. The issue queue is long and it doesn't appear to being actively developed.
