Double Fine have started a Humble Bundle that doesn't gift players with cheap games. Instead, it allows them to vote on four prototype designs that could be made into a full title.
A $1 donation allows you to have your say. You will also receive prototypes from Double Fine's previous Amnesia Fortnight sessions with this payment. This will be Happy Song and Costume Quest. Remember some proceeds will also be going to charity.
