Shadow Wolf by Open Rift
Shadow Wolf sets the player as a wolf who is stealing the farmers sheep. Simple controls make the game quick and players must confuse the farmers and move them into different positions allowing the player to escape through the hole. Simple puzzles and gameplay allowing for a fun time.
Is there an end to it, or are the levels being generated somehow? 33 nights and 96 sheep in, I finally hit a situation I couldn't get out of.
