A ridiculous terminal game to test your ability to judge time.
go get github.com/erinok/howlonghowlong
Run howlonghowlong in a terminal.
Press space to flash the screen.
How long did the screen flash?
100ms? Type 1. 200? Type 2. And so on, up to 9 for 900ms.
After guessing, you'll be shown if your guess was correct. Press space for the next flash.
Your score so far is tallied in columns along the bottom of the screen. The leftmost column is for perfect guesses, the next column for guesses correct +/- 100ms, the next for +/- 200ms, and so on.
Type q.
