Assets
Though it's very unlikely you'd be able to find enough free assets to make your game from while keeping a consistent style, free art assets can be very handy as placeholders in your game to help give others (and yourself!) a glimpse of where the game is heading. It can be very hard to inspire people to the noble effort of a orphan cube, battling for justice and vengeance against the hoards of malevolent spheres!
