Twelve puzzles that punish the move you make before you have finished thinking. Five of them are sokoban in one costume or another — a frog in a tank, a seal on ice, a warehouse of parcels, a worm in a maze, a squirrel building a bridge out of floating logs — and all five share the rule that makes the form work: things can be pushed and never pulled, so a crate in the wrong corner is a level you have to restart. The rest get to the same place by other routes. Brain Jam jams a parking lot, Grazing Giraffe makes your own neck the obstacle, Museum Night Shift asks you to close the hex a thief was going to use, and Find the Key hides the stars down the dead ends.
