Tips and tricks
- Pick one character and one simple combo and repeat it until it is automatic. Consistency wins far more than variety.
- Rematch after a loss immediately. Fighting game skill is muscle memory, and it builds fastest while the previous round is still fresh.

- Special moves are best used to finish a combo or a round, not to open one.
