Micro:bit Reaction Game

# Reaction game
### How does this game work?
A game for two players. The game engine displays an "icon" on the LEDs after a randomly long time (3-10 s) after the game restarts, and at the same time (without delay) starts a tone of 1.5 s. This indicates the start of the game. The player's task is to press the "button" before the opponent. The "button" can be pressed immediately after the LEDs are lit, while the tone is still sounding.
