There's a bug where if you press R to restart a level while still holding down click, the game still thinks you're moving the appendage. If you let go after having restarted, the appendage will be released/moved without costing a turn, which can be used to shave a turn off levels. Worse than that though, if you release at the same time as pressing R, it won't reset that appendage and will instead leave it wherever it was placed. You can use that to bug next to the finish and win in 3 or less turns, or you can bug directly to the finish, winning in zero turns with a time of 0:00 (having a score of zero also causes other minor problems).
