Xor

A number of minor details have altered this remake's gameplay from that of the original, most notably the sequence in which fish and chickens move -- originally all according to type, now individually. Though seemingly a minor detail, it changes more than one level solution.

Other changes include merciful gestures to the player -- originally levels 11, 13 and 15 could only be accessed directly following the completion of levels 10, 12 and 14, respectively, whereas now they can be selected and played at any time. The player can also now choose to keep the screen view centered on their game piece, while the original versions further restricted the amounts of the game board visible at any given point.
