Momentum is king in Sonic the Hedgehog. Unlike many platformers, Sonic doesn't stop on a dime. He builds and loses momentum based on slopes, springs, and his own actions. To master movement, learn to:

- Roll Down Slopes: When Sonic rolls down a slope, he gains significant speed. Use this to your advantage to clear gaps or break through barriers.
- Maintain Speed: Avoid unnecessary stops. Jumping over enemies instead of stopping to attack them can help maintain your flow.
- use Springs and Bumpers: These are designed to propel Sonic. Learn their trajectories and use them to reach higher paths or bypass obstacles.
- Spin Dash for Acceleration: As mentioned, the Spin Dash is your best friend for quickly gaining speed from a standstill or for breaking through destructible blocks.
- Air Control: While limited, you can slightly adjust Sonic's trajectory in the air. This is crucial for landing on small platforms or avoiding hazards.
Practicing these techniques will allow you to navigate levels more efficiently, find hidden areas, and achieve faster completion times.
