 However, within each day, play may be nonlinear.Throughout the game, a running score is kept as new challenges, both required and optional, are completed.Unlike newer graphical adventure games using context-sensitive cursors that change based on what the cursor is hovering over, "Sins of the Fathers" uses "dumb icons" or "dumb cursors" so that the correct cursor must be chosen for a specific interaction with an on- screen object.
