Cafe Leblanc is a unique movie labyrinth that takes the form of a bustling, ever-changing city street, reminiscent of Shibuya. This movie introduces 'Crowd' mechanics and 'Time Limit' puzzles, where you need to navigate through dense crowds or complete objectives within a set number of turns. The atmosphere is vibrant but also carries an underlying sense of urgency and mystery. You'll need to be quick on your feet and strategic in your movements.

The primary mechanic involves 'Crowd Blocks' that obstruct your path and 'Traffic Lights' that control their movement. Some F.O.E.s, like the 'Street Thugs', will only appear or move when certain conditions are met, such as the crowd dispersing. The 'Time Limit' puzzles often involve reaching a specific point or activating a mechanism before a counter reaches zero. Failing these can result in F.O.E. encounters or being forced to restart a section. Careful planning and efficient movement are paramount in this dynamic urban environment.
