The game uses a side-scrolling perspective with direct control over Harley. Players move through rooms, labs, and household spaces rendered as giant obstacle courses, relying on jumps, careful platforming, and item usage to progress. Tools such as rubber bands, thumbtacks, and a jetpack are used to cross gaps, reach higher areas, or trigger solutions to environmental puzzles. Levels mix enemy avoidance, precision jumps, and route-finding, with progress often gated by key items or switches. Checkpoints and retries keep the flow focused on exploration and timing.

Harley

The shrunken scientist protagonist controlled by the player, exploring a giant world to recover his stolen invention.

Learn how each gadget changes movement or interaction, since some sections are designed around one specific tool. Do not rush through enemy-heavy areas; many encounters are easier to bypass than to fight. Watch the scenery for interactive objects and hidden openings, because useful paths are often tucked into corners or props. For difficult jumps, line up carefully and use the smallest safe movement needed to avoid unnecessary falls.
