Why use state machines for a reaction game?

Finite State Machines (FSM) model apps as explicit, predictable states (Idle -> Playing -> GameOver) triggered by events. No more boolean state spaghetti….

We chose XState for Reflex Machine to get:

• ⏱️ Declarative game timers (delays as state transitions)
• 🔒 Input integrity (clicks ignored if round is over)
• ❌ Zero impossible states
