GuffoChallenges are a 2-weeks-long Fancade event created by Guffo (TonoCia0n3). Originally started as a collaborative game jam, it is currently a solo game jam. In the event, a character (which can be found in an editable kit on Fancade) is given to the participants, who then have to make and submit a game involving said character model. Editions usually last 2 weeks, but they can be extended if not enough projects are completed within the deadline.
