advance through 30 levels of increasing puzzle complexity; player can still complete puzzle if time limit runs out - in which case completion is signalled by an amber border as opposed to green.
features an auto-pause that activates after 10 seconds of touch screen inactivity; player can then choose to either continue with current puzzle or go back to select a different level.
randomly generated puzzles offer endless replay and challenge :)
updated! - can now tap on a shape to lock (unlock) it into place.
