How to play
- Wait for green, then react as fast as you can. Reacting before it changes counts as too early.
- From Hard on, some signals are amber decoys: don't react to those — they disappear on their own.
- Extreme and Nightmare show an arrow: press the matching arrow key or button. Nightmare has 8 rounds and the most decoys.
- Your average uses only correct reactions.
