Pro Tips & Strategies

1. Master the bounce chain. Landing on an enemy gives you a small boost. Chain multiple enemy bounces to reach secret areas and high platforms that seem out of reach.

2. Use walls as launchpads. Wall-jumping isn't just for climbing — you can redirect your momentum mid-air to slip past spike traps that look impossible on the first try.

3. Slow down on moving platforms. Most deaths come from rushing. Wait for the platform to reach its apex before jumping, especially in the factory world where timing is everything.
