I haven't pledged but I suppose there's no harm in it as they clearly state that it's "All or nothing. This project will only be funded if it reaches its goal by Wed, December 12 2018 3:30 PM ACDT." All or nothing funding means that no one will be charged for a pledge towards a project unless it reaches its funding goal.
But if they have only reached $500 on their first day, which really should be their biggest funding day I just don't see them making $3.5 million in 40 days. In my opinion I don't think the project will take off at all. Good on those that have pledged, the article on that goto website was well written! I hope they write up more updates during the campaign to entice new people. I want to be impressed but I just don't feel it yet.
