Bob the snail is in the unfortunate position of being a small creature in a big, ever changing world. When his home is destroyed, thanks to new construction, the task falls to players to help him find a new place to live in Snail Bob. By manipulating the environment, help Bob make his way safely through each level. Although Bob only moves in one direction, the player can stop him, start him, and switch between fast and slow speed settings at their discretion. Twenty levels of puzzles and a sizable quantity of different environmental tools flesh this game out well.
